| analysis by the reductive-cleavage method of linkage positions in a polysaccharide containing 4-linked d-glucopyranosyluronic residues. | the fate of 4-linked d-glucopyranosyluronic residues under reductive-cleavage conditions was investigated by using the klebsiella aerogenes type 54 strain a3 capsular polysaccharide. treatment of the fully methylated polysaccharide with triethylsilane and trimethylsilyl trifluoromethanesulfonate in dichloromethane, followed by in situ acetylation, yielded 1,5-anhydro-2,3,4,6-tetra-o-methyl-d-glucitol, 3,4-di-o-acetyl-1,5-anhydro-2,6-di-o-methyl-d-glucitol, and 3-o-acetyl-1,5-anhydro-2,4-di-o-met ... | 1988 | 3288343 |
| common evolutionary origin of the ilvgmeda attenuation locus and trna(1leu) in escherichia coli. | published sequences of transcripts from ilvgmeda leader regions of several enteric bacteria were compared with published sequences of the trnas from escherichia coli. the analyses revealed homology between the ilvgmeda leader peptide-coding region and trna(1leu) in e. coli, salmonella typhimurium, and klebsiella aerogenes, whereas homology was not present in serratia marcescens and edwardsiella tarda. | 1987 | 3294812 |
| evolution of the enterobacterial sula gene: a component of the sos system encoding an inhibitor of cell division. | the lexa-regulated sula (sfia) gene of escherichia coli encodes an unstable protein which inhibits cell division. by determining the nucleotide sequences of the corresponding genes from the related bacteria salmonella typhimurium, enterobacter aerogenes and serratia marcescens it was found that the regulatory region and the lexa binding site (sos box) have been better conserved during evolution than the coding sequence. the n terminus of the sula protein [amino acid (aa) residues 1-30] has diver ... | 1987 | 3297925 |
| incidence of staphylococcus aureus, coliforms and antibiotic-resistant strains of escherichia coli in rural water supplies in port harcourt. | the bacteriological quality of some rural water supplies in port harcourt was monitored over a 3 month period. the supplies were unsatisfactory as judged by standard plate counts (10(3)/ml) and the presence of presumptive and faecal coliforms and staphylococcus aureus. the recovery of potentially pathogenic bacteria (e.g. pseudomonas aeruginosa) further substantiated the existence of health hazards. the most frequently isolated coliforms were escherichia coli, enterobacter aerogenes and klebsiel ... | 1987 | 3298188 |
| biosynthesis of o-succinylbenzoic acid. i: cell free synthesis of o-succinylbenzoic acid from isochorismic acid in enzyme preparations from vitamin k producing bacteria. | escherichia coli k12 and a mutant of e. coli (viz., an 154) as well as aerobacter aerogenes 62-1 (i.e., klebsiella pneumoniae) were used as sources of the enzyme catalyzing the formation of o-succinylbenzoic acid (osb) from isochorismic acid and alpha-ketoglutaric acid in the presence of thiamine pyrophosphate. the product of the reaction (osb) was identified by hplc before and after derivatization to the methylester, dilactone, and coenzyme a ester. osb synthase and alpha-ketoglutarate dehydrog ... | 1987 | 3300552 |
| electron microscopical investigation of citrate lyase single molecules. | electron micrographs of citrate lyase from rhodopseudomonas gelatinosa and klebsiella aerogenes reveal two characteristic molecular forms. the "basket" form and the "star" form were subjected to two-dimensional image reconstruction using a technique involving averaging of superposed single molecular images after rotational correlation. a three-dimensional image reconstruction shows that the images of these forms can be interconverted by rotation and that they therefore represent different views ... | 1987 | 3304340 |
| the k1 beta-lactamase of klebsiella pneumoniae. | beta-lactamase k1 was purified from klebsiella pneumoniae sc10436. it is very similar to the enzyme produced by klebsiella aerogenes 1082e and described by emanuel, gagnon & waley [biochem. j. (1986) 234, 343-347]. an active-site peptide was isolated after labelling of the enzyme with tritiated beta-iodopenicillanate. a cysteine residue was found just before the active-site serine residue. this result could explain the properties of the enzyme after modification by thiol-blocking reagents. the s ... | 1987 | 3307765 |
| isolation from klebsiella and characterization of two rcs genes that activate colanic acid capsular biosynthesis in escherichia coli. | two genes, designated rcsa (regulation of capsule synthesis) and rcsb, that had been cloned from the chromosome of klebsiella aerogenes (k. pneumoniae) capsular serotype k21 were capable of activating expression of colanic acid capsular polysaccharide in escherichia coli k12. the klebsiella rcsa gene encoded a polypeptide of 23 kda that was required for the induction of a mucoid phenotype at less than or equal to 30 degrees c but not at greater than or equal to 37 c. the klebsiella rcsb locus en ... | 1987 | 3309150 |
