| glutamine-binding subunit of glutamate synthase and partial reactions catalyzed by this glutamine amidotransferase. | in the course of studies on glutamine-dependent carbamyl phosphate synthetase from aerobacter aerogenes, we purified another protein which was found to be glutamate synthase (ec 2.6.1.53). the enzyme, obtained in apparently homogeneous form (monomer molecular weight about 227,000; s(20,omega) = 17.6 s), was found to be a typical glutamine amidotransferase in that it exhibits glutaminase activity and can utilize ammonia in place of glutamine as a nitrogen donor. the enzyme also catalyzes at low r ... | 1974 | 4531004 |
| trimethoprim resistance determined by r factors. | r factors conferring a high level of resistance to trimethoprim have been identified in one strain of escherichia coli and one of klebsiella aerogenes, both isolated from infected urines. | 1972 | 4552466 |

| comparison of the substrate specificities of the -lactamases from klebsiella aerogenes 1082e and enterobacter cloacae p99. | a potent beta-lactamase (ec 3.5.2.6) produced by a strain of klebsiella aerogenes (k. pneumoniae), 1082e, isolated from a hospital patient, has been examined. its properties were different from those of most gram-negative beta-lactamases previously reported. the enzyme has been partly purified, and its activity against a range of substrates has been compared with that of the enzyme from enterobacter cloacae (aerobacter cloacae) p99. the k. aerogenes enzyme, although predominantly a penicillinase ... | 1972 | 4553144 |
| isolation of a polyvalent bacteriophage for escherichia coli, klebsiella pneumoniae, and aerobacter aerogenes. | a lytic bacteriophage isolated from sewage was found to attack strains of aerobacter aerogenes, escherichia coli, and klebsiella pneumoniae, but not members of the genera salmonella, proteus, and serratia. the phage, designated phimp, contained deoxyribonucleic acid with a 50% guanine plus cytosine ratio and a molecular weight of 23.1 x 10(6) daltons. single-step growth experiments of phimp plated at 37 c on a. aerogenes a2 gave a mean latent period of 20 min, an average burst size of 103 plaque ... | 1972 | 4554466 |

| partial characterization of phosphoribosyl transferase, phosphoribosyl anthranilate isomerase, and indole glycerol phosphate synthase from serratia marcescens. | the molecular organization of the enzymes phosphoribosyl (pr) transferase, phosphoribosyl anthranilate (pra) isomerase, and indole glycerol phosphate (ingp) synthase of the tryptophan biosynthetic pathway of serratia marcescens was investigated and compared with that reported in other enteric bacteria. pra isomerase and ingp synthase activities were found to reside in a single polypeptide chain, a situation analogous to that in escherichia coli, salmonella typhimurium, and aerobacter aerogenes. ... | 1972 | 4559725 |
| enteric bacterial growth rates in river water. | enteric bacteria, including stocked strains of pathogenic species and organisms naturally present in the stream, were capable of growth in a chemostat with autoclaved river water taken 750 m below a sewage outfall. maximal specific growth rates for all organisms occurred at 30 c, whereas culture generation times ranged between 33.3 and 116 hr. of the six laboratory strains of enteric species used, escherichia coli and enterobacter aerogenes grew at generation times of 34.5 and 33.3 hr, respectiv ... | 1972 | 4561100 |
| erythritol as a selective substrate for the growth of serratia marcescens. | serratia marcescens grew on a basal medium containing 0.5% erythritol as sole source of carbon for growth and energy. only an occasional strain of enterobacter aerogenes among several members of the family enterobacteriaceae were able to utilize erythritol. | 1972 | 4561106 |
| inhibition of the -lactamases of escherichia coli and klebsiella aerogenes by semi-synthetic penicillins. | 1. a new automated micro-iodometric method is described for screening compounds for inhibitory action against beta-lactamase enzymes. 2. over 1000 semi-synthetic penicillins were tested for inhibitory activity against the beta-lactamase of escherichia coli b11 and 18 showed a fractional inhibition similar to or higher than that of methicillin. 3. the best inhibitors were alkoxy- and halogen-substituted phenyl-, naphthyl- or quinolyl-penicillins. 2-isopropoxy-1-naphthylpenicillin (brl 1437) was c ... | 1972 | 4561388 |
