    Notes:
    Vacuum-ultraviolet photoionization molecular-beam mass spectrometry is a means of identifying primary photodissociation products and determining their recoil energies. At several photolysis wavelengths between 220 and 320 nm, we have observed three primary photodissociation pathways for nitrobenzene. Two of the pathways are C6H5NO2 →C6H5+NO2 and C6H5NO2→C6H5NO+O. The third pathway produces NO by one or both of the processes C6H5NO2→C6H5O+NO and C6H5NO2→C5H5+CO+NO. The relative yield of the pathways producing NO2 and NO varies strongly with the photolysis wavelength. The production of NO2 exceeds that of NO by about 50% for the 280 nm photolysis, but increases to almost a sixfold excess in 222 nm dissociation. The second pathway has a threshold energy that is about 0.50 eV greater than the thermodynamic limit for the formation of nitrosobenzene (C6H5NO) and an oxygen atom from nitrobenzene, probably reflecting the energy required to produce triplet nitrosobenzene and, perhaps, a barrier to dissociation on the triplet surface. The distribution in arrival times for a fragment provides an estimate of the recoil energy at each photolysis wavelength in these experiments. The channel producing nitric oxide (NO) radicals releases a relatively large amount of kinetic energy. Assuming the channel producing nitric oxide (NO) also produces phenoxy (C6H5O), we calculate a linear increase in kinetic energy from 0.29 eV at 320 nm to 1.1 eV at 220 nm. By contrast, the other two channels release only a small amount of kinetic energy (≈0.1 eV) at all wavelengths. An impulsive model does not describe the observed kinetic energy release for these low energy channels, suggesting that the energy release is more nearly statistical. The recoil energy predicted by an impulsive model for the channel producing nitric oxide and phenoxy radicals is closer to the observed kinetic energy release.

    Notes:
    Laser induced fluorescence probing of the nitric oxide fragment determines the distribution of rotational and vibrational energies of NO produced in the 226 and 280 nm photolysis of nitrobenzene. Combining these results with kinetic energy measurements using vacuum ultraviolet photoionization to detect the fragment gives a detailed view of the energy release in the photolysis. Boltzmann distributions describe the rotational state populations at both photolysis wavelengths. The rotational temperature of NO from the 226 nm photolysis is (3700±350) K, corresponding to an average rotational energy of (0.32±0.03) eV, and that of NO from the 280 nm photolysis is (2400±200) K, corresponding to an average rotational energy of (0.20±0.03) eV. We observe no vibrationally excited NO and place an upper limit of 10% on the fraction of nitric oxide produced in any one vibrationally excited state. Two different limiting models, impulsive energy release and statistical energy redistribution, both correctly predict much more rotational than vibrational excitation, but neither completely describes the observed internal and kinetic energies. The impulsive model finds more NO rotational and translational energy, but much less phenoxy fragment internal energy than we observe. The statistical model does better for the NO rotation and phenoxy fragment internal energy, but underestimates the translational energy substantially. A combination of these two types of behavior provides a physical picture that qualitatively explains our observations. It is likely that statistical energy redistribution occurs during the approach to the transition state for isomerization of nitrobenzene to phenyl nitrite and impulsive energy release dominates during the subsequent rupture of the CO–NO bond.

    Notes:
    Juvenile hormone esterase (JHE) activity released by the corpora allata (CA) into incubation media (CA-JHE) was titered daily during the course of the last (fifth [V]) larval stadium of Manduca sexta. This CA-JHE activity was relatively low during the early last stadium up to the time of commitment (V4), then rose rapidly to a peak on V6. Activity declined sharply almost to precommitment levels by V8, before rising to a second peak on the first day of the pupal phase (P0). This pattern of activity is distinct from that of hemolymph JHE activity, which peaks just prior to wandering on V4 and again just prior to pupation (V9). Although the CA-JHE and hemolymph-JHE possess different temporal patterns of activity, isoelectric focusing, gel electrophoresis, and initial studies with selected inhibitors suggest that the enzymes responsible for the CA-JHE and hemolymph-JHE activities are similar, but not identical, in nature.Exposure of the V6 CA in vitro to JH II (0.1 μM) or fluoromevalonolactone (FMev; 0.1 mM) produced an approximate fivefold increase and 60% decrease in JH acid synthesis, respectively. Conversely, the same treatments resulted in an inhibition (JH II) and stimulation (FMev) of CA-JHE activity. These observations suggest that JH may be involved in the direct positive feedback regulation of postwandering larval CA and that the CA-JHE may also be integrally related to this positive feedback mechanism.

    Notes:
    An assay was developed with which to study basic characteristics of an adenylyl cyclase in the corpora allata (CA) of the tobacco hornworm, Manduca sexta. The assay used glands collected and frozen at -80°C, to circumvent the problem of tissue availability. With this protocol for storage of tissue, less than 25% of the enzyme activity in fresh tissue was lost. Substances such as sodium fluoride (NaF) and Gpp(NH)p (a non-hydrolyzable GTP analog), which typically stimulate the adenylyl cyclases in other insect tissues, increased enzyme activity several-fold. There was a progressive decrease in the capacity of the CA adenylyl cyclase to be stimulated by NaF during the fifth stadium, suggesting a possible developmental change in the capacity of the associated G protein to be stimulated by NaF. The calcium/calmodulin (CaM) dependence of adenylyl cyclase activity was also investigated. The results demonstrated that addition of up to 10-4 M calcium to assays of enzyme activity in whole gland homogenates of both larval (day O) and prepupal (day 6) CA resulted in only a slight increase in the activity of the enzyme over basal rates in the presence of the calcium chelator EGTA. However, addition of as little as 5 m̈M CaM in the presence of 10-4 to 10-3 M calcium increased adenylyl cyclase activity three to five-fold. A similar stimulation was obtained with washed membrane preparations of day 0 and day 6 glands, but required a substantially higher concentration of CaM. Results demonstrated that the CA possess a calcium/CaM-dependent adenylyl cyclase from day 0 through day 6. A preliminary investigation of the effect of two biogenic amines on the CA adenylyl cyclase revealed that enzyme activity was not affected by octopamine, but a stage-specific effect was obtained with dopamine. Concentrations of 10-6 and 10-7 M stimulated enzyme activity in hornogenates of day 0 glands but inhibited activity in homogenates of day 6 CA. © 1995 Wiley-Liss, Inc.
