lifetime of messenger ribonucleic acid for penicillinase synthesis in several strains of bacilli.1. previous studies of penicillinase synthesis in bacillus licheniformis showed that enzyme synthesis after the addition of actinomycin continues for far longer in the constitutive mutant 749/c than in the parental inducible strain (yudkin, 1966). this result was interpreted as indicating a difference in the lifetime of specific messenger rna in the two strains. other bacilli have now been examined in an attempt to see whether this difference is general. 2. there was no difference in the lifetim ...19684969990
synthesis of teichoic acids. vii. synthesis of teichoic acids during spore germination.the synthesis of teichoic acids has been examined during germination in bacillus licheniformis atcc 9945 and in b. subtilis w-23. teichoic acids are absent from the spores of both organisms. b. licheniformis spores lack the enzymes responsible for teichoic acid synthesis. the appearance of these enzymes during germination is correlated with the appearance of teichoic acids in the cell. the appearance of teichoic acid-synthesizing enzymes and of teichoic acids in the cell are inhibited by the add ...19684970221

characteristics of secretion of penicillinase, alkaline phosphatase, and nuclease by bacillus species.the distribution of alkaline phosphatase and nuclease activity between cells and medium was examined in one strain of bacillus licheniformis and four strains of b. subtilis. over 95% of both activities was found in the medium of the b. licheniformis culture, but in the b. subtilis cultures the amount of enzyme activity found in the medium varied with the strain and the enzyme considered. b. licheniformis 749 and its penicillinase magnoconstitutive mutant 749/c were grown in continuous culture wi ...19684970649
diaminopimelate decarboxylase of sporulating bacteria.the meso-diaminopimelate (dap) decarboxylase of bacillus licheniformis, a pyridoxal phosphate-requiring enzyme, was stabilized in vitro by 0.15 m sodium phosphate buffer (ph 7.0) containing 1 mm 2,3-dimercaptopropan-1-ol, 100 mug of pyridoxal phosphate per ml, and 3 mm dap. when the meso-dap concentration was varied, the enzyme in cell-free extracts of b. licheniformis exhibited michaelis-menten kinetics. pyridoxal phosphate was the only pyridoxine derivative which acted as a cofactor. the enzym ...19684972917
localization of cell-bound penicillinase in bacillus licheniformis.when protoplasts are prepared from bacillus licheniformis (strain 749/c, constitutive for penicillinase), approximately 60% of the cell-bound penicillinase is released. the remainder is retained by the protoplast and cannot be removed by washing. this release is specific, in that less than 7% of the cellular reduced nicotinamide adenine dinucleotide (nadh) dehydrogenase and alpha-glucosidase is liberated by the treatment. the freed penicillinase is excluded from g-200 sephadex, and it is partial ...19684302175
some enzymic activities and chemical properties of the mesosomes and cytoplasmic membranes of bacillus licheniformis 6346.1. the liberation of the vesicles of the mesosomes from protoplasts of bacillus licheniformis strain 6346 is controlled by the mg(2+) concentration present during the removal of the walls by lysozyme. 2. the functioning of the cytoplasmic membranes is also critically controlled by the mg(2+) concentration. 3. the isolated mesosomes and the cytoplasmic membranes differ in their enzymic activities. both succinate dehydrogenase and nadh oxidase activities are very low or absent from the mesosomes. ...19694308839
regulated enzymes of aromatic amino acid synthesis: control, isozymic nature, and aggregation in bacillus subtilis and bacillus licheniformis.several regulated enzymes involved in aromatic amino acid synthesis were studied in bacillus subtilis and b. licheniformis with reference to organization and control mechanisms. b. subtilis has been previously shown (23) to have a single 3-deoxy-d-arabinoheptulosonate 7-phosphate (dahp) synthetase but to have two isozymic forms of both chorismate mutase and shikimate kinase. extracts of b. licheniformis chromatographed on diethylaminoethyl (deae) cellulose indicated a single dahp synthetase and ...19694977689
cotransduction and cotransformation of genetic markers in bacillus subtilis and bacillus licheniformis.bacteriophage sp-15, a large generalized transducing phage of bacillus, was compared with phages pbs-1 and sp-10 for the ability to cotransduce pairs of genetic markers exhibiting different degrees of linkage. when auxotrophs of b. subtilis w-23 were used as recipients, sp-15 and pbs-1 effected a much higher frequency of cotransduction than did sp-10 with markers that were not closely linked. with more closely linked loci, the differences were not as great. sp-15 cotransduced linked markers at a ...19694982666

a mechanism for penicillinasesecretion in bacillus licheniformis.cell-bound isozymes of penicillinase are distinguished from extracellular enzyme by their capacity to bind deoxycholate and to elute with an apparent molecular weight of 45,000 on gel filtration in its presence. by methods that are unlikely to involve changes in primary structure, the cell-bound forms (both from the plasma membrane and from the periplasmic vesicles) can be converted to forms that are very similar if not identical to the exo-form (i.e., eluting with a molecular weight of 24,000 i ...19705266165
the preparation of iodinated vancomycin and its distribution in bacteria treated with the antibiotic.vancomycin was radioactively labelled by iodination with (125)i.iodinated vancomycin was only a little less potent as an antibiotic than vancomycin itself. it was shown, both by chromatography and differential absorption measurements, to combine with acyl-d-alanyl-d-alanine residues. radioactive vancomycin was used to follow the fate of the antibiotic in bacteria that had been subjected to the least concentration required to inhibit growth. most of the radioactivity was in the cell walls, althou ...19705411430
