Published 1990Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: The rate of the association reaction, BH+D2→BHD2 is determined both theoretically and experimentally. In the theoretical calculations, potential-energy surface information is obtained using multiconfiguration self-consistent-field and large-scale multireference configuration-interaction calculations with large correlation consistent basis sets. The preferred direction of approach is found to be along a non-least-motion pathway for which the BH and DD bonds come in nearly parallel to one another. The small computed activation energy of 2.6 kcal/mol for this highly exothermic reaction is found to arise almost exclusively from changes in zero-point vibrational energy. The experimental measurements of the BH disappearance rate are made at temperatures from 298 to 597 K and are shown to be only weakly dependent on total pressure over the range of 1–100 Torr. As a test of the proposed mechanism, we observe the growth of BD and find the BD appearance rate constant to be in excellent agreement with that for BH disappearance. The measured reaction rates are compared to the results of canonical variational transition-state theory calculations of the association rate and are found to be in excellent agreement.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: In this report, we describe some general features of the monotonic Lagrangian grid (MLG) that are important in molecular dynamics simulations. The monotonic Lagrangian grid is a highly efficient and general algorithm for tracking particles and computing interactions in simulations of systems consisting of large numbers of particles. Further, the MLG algorithm is highly adaptable to vector or parallel processing. The mode of implementing the MLG algorithm depends on the nature of the particle simulation. We present results of simulations for calculating the dimer mole fraction as a function of temperature in a three-dimensional N2 gas system. The results are consistent with experimental and theoretical results and demonstrate the effectiveness of the MLG algorithm in simulating gas systems and monitoring dynamically rare processes.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: Features of the potential energy surface pertinent to the thermal decomposition mechanism of methylenenitramine (CH2NNO2) are investigated. At issue are the activation energies both for concerted molecular dissociation leading to HCN and HONO and for the simple NN bond cleavage leading to CH2N and NO2. We use multiconfiguration (MC)SCF wave functions with double-zeta and double-zeta plus polarization quality basis sets to locate minimum energy and transition state structures as well as determine harmonic vibrational frequencies and resulting zero-point vibrational energies. The energetics are determined using configuration interaction wave functions which include single and double excitations from a selected set of reference configurations constructed with the MCSCF molecular orbitals. Our best calculations, without adjustment, predict the molecular dissociation to have an activation energy slightly lower than that for simple bond rupture. Calculations at the level of those reported here are known, however, to underestimate bond dissociation energies by several kcal/mol. Based on trends from past calculations, and new calculations on a related compound, we estimate the activation energy for the HONO elimination path to be 31±4 kcal/mol and the NN bond dissociation energy to be 35±4 kcal/mol. This reverses the energetic ordering of previous theoretical predictions and is consistent with recent molecular beam experiments.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A coolable gas cell for the measurement of mid-infrared spectra of gases at cryogenic temperatures as low as 77 K is described. The design of the cell allows it to be operated in collisional cooling (or diffusive trapping) mode to generate significant nonequilibrium pressures of monomer vapor for gases which would normally have vanishingly small vapor pressure at low temperatures. Fourier transform infrared spectra of carbon dioxide (CO2), nitrogen dioxide (NO2), and methyl silane (CH3SiH3) vapors cooled by collisions with helium gas at 77 K are reported. Sufficiently high concentrations of monomer gas may be produced at low total pressure conditions (〈10 h Pa) to allow spectra to be recorded at the Doppler resolution limit. The resulting spectroscopic simplification indicates that efficient collisional cooling of the vibrational, as well as rotational, degrees of freedom occurs. © 1995 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1985Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: The collinear dynamics of a model diatom–diatom system is investigated. The collision partners are harmonic oscillators for which the masses and force constants are chosen to correspond to those of the nitrogen and oxygen molecules. The interaction between the molecules arises from a Lennard-Jones 6-12 potential acting between the inside atoms in the collinear system. Quantum mechanical close coupled calculations are performed for several collision energies ranging from 1.0 to 2.25 eV. The state-to-state transition probabilities which are extracted from these calculations are then used as a benchmark for comparison. Semiclassical calculations are performed within the framework of a classical path approximation. A simple scheme to modify the classical path to reflect energy exchange between the collision coordinate and the internal degrees of freedom is found to improve the results. On the whole, the agreement between the semiclassical and the quantum mechanical results is surprisingly good. The classical trajectory calculations correctly display many of the qualitative features of the collisions but the numerical agreement is not as close. Unexpectedly, the classical results do not appear to be improving as the collision energy is increased.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1365-2826Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Increasing concentrations of D-glucose (1 to 25 mM) inhibited somatostatin, thyrotrophin-releasing hormone (TRH) and growth hormone-releasing hormone (GHRH) release from incubated adult rat hypothalami in a stereospecific manner. In contrast, the effects of D- and L-glucose on luteinizing hormone-releasing hormone release were virtually identical. Increasing concentrations of D-glucose also inhibited somatostatin release following depolarization with high K+, but had no obvious effect on depolarization-induced TRH or GHRH release when compared with L-glucose.In conclusion, D-glucose exerts a potent, dose-related modulatory action on the release of rat hypothalamic TRH and GHRH as well as somatostatin in vitro. Further studies are required to establish any physiological relevance of glucose in the modulation of these hypothalamic neuropeptides.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1365-2826Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: We describe the development and validation of a two-site immunochemiluminometric assay for rat growth hormone-releasing hormone (GHRH) based on the affinity purification of polyclonal rabbit antisera to rat GHRH using a human 1–29 GHRH affinity column. Assay sensitivity is 3.2 pg/ml using 100 μl of unextracted sample and the working range for the assay within 15% confidence limits is 64 to 5,000 pg/ml. Rat hypothalamic extract and secreted material demonstrated a single large peak of immunoreactive material coeluting with synthetic rat GHRH on high-performance liquid chromatography with a smaller, earlier peak which probably represents methionine sulphoxide [Met(O)27] GHRH. Extracted material diluted in parallel to the standard curve. Incubated rat hypothalami readily released measurable amounts of rat GHRH which responded appropriately to depolarization with 60 mM K+ in a Ca2+-dependent manner.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1365-2958Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyMedicineNotes: DipZ is a bacterial cytoplasmic membrane protein that transfers reducing power from the cytoplasm to the periplasm so as to facilitate the formation of correct disulphide bonds and c-type cytochromes in the latter compartment. Topological analysis using gene fusions between the Escherichia coli dipZ and either E. coli phoA or lacZ shows that DipZ has a highly hydrophobic central domain comprising eight transmembrane α-helices plus periplasmic globular N-terminal and C-terminal domains. The previously assigned translational start codon for the E. coli DipZ was shown to be incorrect and the protein to be larger than previously thought. The experimentally determined translational start position indicates that an additional α-helix at the N-terminus acts as a cleavable signal peptide so that the N-terminus of the mature protein is located in the periplasm. The newly assigned 5′ end of the dipZ gene was shown to be preceded by a functional ribosome-binding site. The hydrophobic central domain and both of the periplasmic globular domains each have a pair of highly conserved cysteine residues, and it was shown by site directed mutagenesis that all six conserved cysteine residues contribute to DipZ function.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2958Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyMedicineNotes: An apo form of cytochrome C550 can be detected by immunoblotting cell-free extracts of a mutant of Paracoccus denitrificans that is deficient in c-type cytochromes. This apoprotein is found predominantly in the periplasm, the location of the holocytochrome in the wild-type organism, indicating that translocation of the polypeptide occurs in the absence of haem attachment. The polypeptide molecular weight, as judged by sodium dodecyl sulphate/polyacrylamide gel electrophoresis, is indistinguishable from that of the holoprotein and the chemically prepared apoprotein; this suggests that the N-terminal signal sequence is removed in the mutant as in the wild-type organism. In the presence of levulinic acid, an inhibitor of haem biosynthesis, apocytochrome c550 and aponitrite reductase (cytochrome cd1) accumulated in the periplasm of wild-type cells. Synthesis of these apoproteins was blocked by chloramphenicol. Thus in P. denitrificans the synthesis of these polypeptides is neither autoregulated nor regulated by the availability of haem. That the apoproteins appear in the periplasm argues against the possibility of polypeptide/haem co-transport from cytoplasm to periplasm. These observations are related to, and contrasted with, the biosynthesis of c-type cytochromes in eukaryotic cells.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2958Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyMedicineNotes: An apo form of cytochrome cd1, (nitrite reductase) of Paracoccus denitrificans has been detected immunologically in the periplasm of a mutant that lacks all c-type cytochromes. A method for the preparation of apo-nitrite reductase (lacking both c- and d-type haem) from the holoenzyme of wild-type cells has been developed. The apoprotein synthesized by the mutant is indistinguishable from the chemically prepared apoprotein in respect of: (i) subunit molecular weight; (ii) formation of a homodimer; (iii) properties on anion exchange chromatography. The holoenzyme has similar properties in respect of (i) and (ii) but behaves differently during anion exchange. A suggested mode of assembly of cytochrome cd1, is trans-location into the periplasm of a precursor polypeptide, maturation by a signal peptidase to give an apoprotein identical to that prepared chemically from the holoenzyme, followed by insertion of c-type and d-type haem in an as yet unknown order.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2958Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyMedicineNotes: Cloning and sequencing of the Paracoccus denitrificans ccmG gene indicates that it codes for a periplasmic protein–disulphide oxidoreductase; the presence of the sequence Cys-Pro-Pro-Cys at the CcmG active site suggests that it may act in vivo to reduce disulphide bonds rather than to form them. A CcmG–PhoA fusion confirmed the periplasmic location. Disruption of the ccmG gene resulted in not only the expected phenotype of pleiotropic deficiency in c-type cytochromes, but also loss of spectroscopically detectable cytochrome aa3, cytochrome c oxidase and ascorbate/TMPD oxidase activities; there was also an enhanced sensitivity to growth inhibition by some component of rich media and by oxidized thiol compounds. Dithiothreitol promoted the growth of the ccmG mutant on rich media and substantially restored spectroscopically detectable cytochrome aa3 and cytochrome c oxidase activity, although it did not restore c-type cytochrome biogenesis. Assembly of the disulphide-bridged proteins methanol dehydrogenase and Escherichia coli alkaline phosphatase was unaffected in the ccmG mutant. It is proposed that P. denitrificans CcmG acts in vivo to reduce protein–disulphide bonds in certain protein substrates including c-type cytochrome polypeptides and/or polypeptides involved in c-type cytochrome biogenesis.Type of Medium: Electronic ResourceURL:
