Published 1992Staff ViewISSN: 1365-2958Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyMedicineNotes: CS1 pili are filamentous proteinaceous appendages found on many enterotoxigenic Escherichia coli (ETEC) strains isolated from human diarrhoeal disease. They are thought to effect colonization of the upper intestine by facilitating binding to human ileal epithelial cells. We have identified a gene, cooB, which lies directly upstream of cooA, the gene that encodes the major structural CS1 protein. When translated in vitro, the protein product of cooB migrates in sodium dodecyl sulphate/polyacrylamide gel with an apparent molecular mass of 26 kDa, which is consistent with that predicted from its DNA sequence. We constructed a mutant allele (cooB-1) by insertion of the omega fragment, which inhibits transcription and translation, into the cooB gene in vitro. In a derivative of an ETEC strain with the cooB-1 mutation (JEF100) and a plasmid that encodes Rns (pEU2030), the positive regulator required for CS1 expression, no cooB and a greatly reduced level of cooA product was detectable in total cell extracts. The reduction of cooA in this strain appears to result from polarity of the cooB mutation because introduction of the wild-type cooA gene in trans causes production of CooA protein, which is found in cell pellet extracts, in extracts containing only surface proteins and in the culture supernatant. Therefore, in the absence of CooB, CooA is stable and it is transported through both inner and outer membranes. However, the cooB-1 strain with cooA in trans does not cause haemagglutination of bovine erythrocytes (the model system used to assay adherence mediated by coli surface antigen 1 (CS1) pili). Electron microscopy reveals that there are no pili present on the cell surface or in the culture medium in which this strain was grown. Thus, although it is not required for stability or transport of the major CS1 pilin protein, CooB is needed for assembly of CooA into pili. The relationship of these gene products to those of other pili is discussed.Type of Medium: Electronic ResourceURL: -

We review the size and function of both soluble organic N extracted from soils (SON) and dissolved organic N present in soil solution and drainage waters (DON) in arable agricultural soils. SON is of the same order of magnitude as mineral N and of equal size in many cases; 20–30 kg SON-N ha–1 is present in a wide range of arable agricultural soils from England. Its dynamics are affected by mineralisation, immobilisation, leaching and plant uptake in the same way as those of mineral N, but its pool size is more constant than that of mineral N. DON can be sampled from soil solution using suction cups and collected in drainage waters. Significant amounts of DON are leached, but this comprises only about one-tenth of the SON extracted from the same soil. Leached DON may take with it nutrients, chelated or complexed metals and pesticides. SON/DON is clearly an important pool in N transformations and plant uptake, but there are still many gaps in our understanding.Type of Medium: Electronic ResourceURL: -
