peptide hydrolase activity of klebsiella aerogenes.		1969	5767044
effect of growth rate on histidine catabolism and histidase synthesis in aerobacter aerogenes.	a study was made of how the catabolism of a carbon and energy source is affected by the biosynthetic demands of growing bacterial cells. cultures of aerobacter aerogenes in l-histidine medium were grown in a chemostat at rates determined by the supply of either sulfate or a required amino acid, l-arginine. it was discovered that the rate at which these cells grow under a biosynthetic restriction determines both the rate and the pattern of histidine degradation. (i) histidine catabolism is partia ...	1969	5781570

requirement for sodium in the anaerobic growth of aerobacter aerogenes on citrate.	anaerobic growth of aerobacter aerogenes on citrate as a carbon source required the presence of na(+). the growth rate increased with increasing na(+) concentration and was optimal at 0.10 m na(+). the requirement was specific for na(+), which could not be replaced by k(+), nh(4) (+), li(+), rb(+), or cs(+). k(+) was required for growth in the presence of na(+), the optimal k(+) concentration being 0.15 mm. enzyme profiles were determined on cells grown in three different media: (i) intermediate ...	1969	5784198
induction and properties of the citrate transport system in aerobacter aerogenes.	the mediated transport of citrate in aerobacter aerogenes was studied. according to data obtained by examining the distribution of radioactive citrate at room temperature and at 0 c, a carrier system appears to be located on the membrane. the carrier system is inducible and very specific, not acting on the related compounds isocitrate and cis-aconitate. induction required synthesis of both ribonucleic acid and protein as determined by starving auxotrophic mutants and by using specific inhibitors ...	1969	5784212
role of sodium in determining alternate pathways of aerobic citrate catabolism in aerobacter aerogenes.	in contrast to the absolute na(+) requirement for anaerobic growth of aerobacter aerogenes on citrate as sole carbon source, aerobic growth of this microorganism did not require the presence of na(+). however, na(+) (optimal concentration, 10 mm) did increase the maximal amount of aerobic growth by 60%, even though it did not change the rate of growth. this increase in growth was specifically affected by na(+), which could not be replaced by k(+), nh(4) (+), li(+), rb(+), or cs(+). enzyme profil ...	1969	5808070

isolation of klebsiella aerogenes mutants cis-dominant for glutamine synthetase expression.	we have isolated three strains of klebsiella aerogenes that failed to show repression of glutamine synthetase even when grown under the most repressing conditions for the wild-type strain. these mutant strains were selected as glutamine-independent derivatives of a strain that is merodiploid for the glna region and contains a mutated glnf allele. the mutation responsible for the gln+ phenotype in each strain was tightly linked to glna, the structural gene for glutamine synthetase, and was domina ...	1980	6102550
purification of glutamine synthetase from a variety of bacteria.	we have developed two procedures which allow the very rapid purification of glutamine synthetase (gs) from a diverse variety of bacteria. the first procedure, based upon differential sedimentation, depends upon the association of gs with deoxyribonucleic acid in cell extracts. the second procedure, derived from the method of c. gross et al (j. bacteriol. 128:382-389, 1976) for purifying ribonucleic acid polymerase by polyethylene glycol (peg) precipitation, enabled us to obtain high yields of gs ...	1980	6102984

regulation of the synthesis of glutamine synthetase by the pii protein in klebsiella aerogenes.	certain mutations at the glab locus result in the failure to fully derepress glutamine synthetase [l-glutamate:ammonia ligase (adp-forming), ec 6.3.1.2] and to convert it to the active nonadenylylated form in response to nitrogen limitation. in these mutants the pii regulatory protein is altered such that it cannot be converted by uridylyltransferase to the form stimulating deadenylylation of glutamine synthetase by adenylyltransferase. additional mutations as well as insertions of transposon tn ...	1980	6104810
tryptophan metabolism in klebsiella aerogenes: regulation of the utilization of aromatic amino acids as sources of nitrogen.	klebsiella aerogenes utilized aromatic amino acids as sole sources of nitrogen but not as sole sources of carbon. k. aerogenes abstracted the alpha-amino group of these compounds by transamination and excreted the arylpyruvate portions into the medium. when tryptophan was utilized as the sole source of nitrogen by k. aerogenes, indolepyruvate was excreted into the medium, where it polymerized non-enzymatically to form a brick red pigment. at least four separate aromatic aminotransferase activiti ...	1981	6109705
regulation of glutamine synthetase by regulatory protein pii in klebsiella aerogenes mutants lacking adenylyltransferase.	a mutation of klebsiella aerogenes causing production of an altered pii regulatory protein which stimulates overadenylylation of glutamine synthetase and also prevents its derepression was combined with mutations abolishing the activity of adenylyltransferase. the results support the idea that pii plays a role in the regulation of the level of glutamine synthetase which is independent of its interaction with adenylyltransferase.	1981	6111558
role of glna-linked genes in regulation of glutamine synthetase and histidase formation in klebsiella aerogenes.	we isolated mutants of klebsiella aerogenes with insertions of transposon tn5 linked to the structural gene for glutamine synthetase, glna. we found that k. aerogenes, like escherichia coli and salmonella typhimurium, contains a regulatory gene, glng, which is closely linked to but distinct from glna. the product of glng is essential for normal regulation of the synthesis of glutamine synthetase and histidase. we analyzed two mutations which affected the regulation of the formation of these enzy ...	1982	6120931
effects of glnl and other regulatory loci on regulation of transcription of glna-lacz fusions in klebsiella aerogenes.	mutants of klebsiella aerogenes containing genetic fusions of glna to lacz were isolated by using mu dl (lac, bla) bacteriophage and a mu kmr helper phage with the host range of bacteriophage p1. synthesis of beta-galactosidase in these strains is regulated in response to nitrogen metabolites and regulatory gln loci and is rendered constitutive by a mutation in the linked glnl gene. complementation studies indicated that glnl is a separate locus from glna and glng and that insertions in glna are ...	1982	6120932
asparagine synthetases of klebsiella aerogenes: properties and regulation of synthesis.	we isolated pleiotropic mutants of klebsiella aerogenes with the transposon tn5 which were unable to utilize a variety of poor sources of nitrogen. the mutation responsible was shown to be in the asnb gene, one of two genes coding for an asparagine synthetase. mutations in both asna and asnb were necessary to produce an asparagine requirement. assays which could distinguish the two asparagine synthetase activities were developed in strains missing a high-affinity asparaginase. the asna and asnb ...	1982	6125499
a nonsense mutation in the structural gene for glutamine synthetase leading to loss of nitrogen regulation in klebsiella aerogenes.	an amber mutation (glna3711), the first nonsense mutation isolated in klebsiella aerogenes, is described. when amber suppressors were present, the mutant made active glutamine synthetase which was more thermolabile than wild type, showing that glna3711 lies in the structural gene for glutamine synthetase. strains carrying the glna3711 allele were unable to express nitrogen regulation of genes coding for histidase, asparaginase, and glutamate dehydrogenase unless amber suppressors were also prese ...	1982	6129565

effect of iron deprivation on the production of siderophores and outer membrane proteins in klebsiella aerogenes.	the outer membrane (om) protein profile of klebsiella aerogenes grown in an iron rich chemically defined medium (fe + cdm) showed three major proteins of 32.5, 35.5 and 39.0 kdal. the 35.5 and 39.0 kdal proteins were non-covalently associated with peptidoglycan. at least six new iron regulated outer membrane proteins (irmp) of 69, 70, 73, 75, 78 and 83 kdal, which were not peptidoglycan associated, were apparent in the om of k. aerogenes grown in iron restricted (serum) or iron deficient (fe-cdm ...	1984	6239009
in vitro activity of pefloxacin compared to that of quinolones and other antimicrobial agents.	pefloxacin is a new methyl-4-piperazinyl quinolone. it had mic90 values of less than 0.01 to 0.8 micrograms/ml for the majority of escherichia coli, klebsiella, oxytoca, citrobacter, providencia, enterobacter cloacae, enterobacter aerogenes, morganella and proteus mirabilis. it inhibited ampicillin, cephalexin and nalidixic acid resistant isolates of these species. against pseudomonas the pefloxacin mic90 was 3.1 micrograms/ml. staphylococcus aureus had a mic50 of 0.4 micrograms/ml and a mic90 o ...	1984	6241847
genetic control of tyramine oxidase, which is involved in derepressed synthesis of arylsulfatase in klebsiella aerogenes.	mutants of klebsiella aerogenes with three types of mutations affecting regulation of tyramine oxidase were isolated by a simple selection method. in the first type, the mutation (tynp) was closely linked to the structural gene for tyramine oxidase tyna). the order of mutation sites was atsa-tynp-tyna. in the second type, the mutation that relieves catabolite repression of the syntheses of several catabolite repression-sensitive enzymes are not linked to the tyn gene by p1 transduction. these st ...	1980	6249789
physical maps of klebsiella aerogenes and salmonella typhimurium hut genes.	the recognition sites for several restriction endonucleases were mapped within deoxyribonucleic acid coding for histidine utilization (hut) genes of salmonella typhimurium and klebsiella aerogenes. deoxyribonucleic acid fragments containing the two hut promoters were identified by ribonucleic acid polymerase binding.	1981	6257644
