the biosynthesis of biotin in growing yeast cells: the formation of biotin from an early intermediate. | 1. yeast cells grown in the presence of an unknown radioactive biotin vitamer produced by penicillium chrysogenum incorporated the vitamer into the newly synthesized biotin. 2. the biotin was isolated as the avidin-biotin complex and after hydrolysis the biological activity and radioactivity were shown to be coincidental. 3. the specific activity of the biotin was identical with that of the pimelic acid used in a previous investigation to label the unknown vitamer. 4. the role of the unknown bio ... | 1966 | 16742431 |
an early intermediate in the biosynthesis of biotin: incorporation studies with [1,7-c(2)]pimelic acid. | 1. an unknown biotin vitamer was obtained in high yields in culture filtrates of penicillium chrysogenum. 2. production of this vitamer and desthiobiotin is controlled by the biotin concentration in the medium. 3. the unknown vitamer becomes labelled when the organism is grown in the presence of radioactive pimelic acid. 4. chromatographic procedures were developed for the purification of the radioactive vitamer. 5. the vitamer is extremely stable in concentrated acid but gives rise to new vitam ... | 1966 | 16742432 |
biological breakdown of benzylpenicillin by preformed mats of penicillin-producing organisms. | 1. penicillium chrysogenum and aspergillus flavus degraded benzylpenicillin in the same way. 2. degradation of the antibiotic was initiated by the cleavage of phenylacetic acid from 6-aminopenicillanic acid. 3. phenylacetic acid was left unchanged whereas 6-aminopenicillanic acid was degraded into cysteine and valine. this reaction is probably complex. 4. cysteine was not utilized but valine was cleaved into acetone and glycine. catabolism of valine by the preformed mats of the two moulds confir ... | 1966 | 16742463 |
nonessentiality of boron in fungi and the nature of its toxicity. | an investigation was undertaken to determine whether any of the following fungi had a requirement for boron (b): saccharomyces cerevisiae, aspergillus niger, neurospora crassa, and penicillium chrysogenum. boron was unessential, and hence a study was made of the concentrations of b that reduced the growth of s. cerevisiae and p. chrysogenum and the mode of action of the b toxicity. fifty and 4000 mg b/liter, respectively, significantly (5% level) reduced the growth of the latter 2 species.in bot ... | 1966 | 16656256 |
effect of growth rate on the synthesis of penicillin by penicillium chrysogenum in batch and chemostat cultures. | the kinetics of penicillin production by penicillium chrysogenum wis 54-1255 in a glucose-limited chemostat and in batch cultures are reported. the specific production rate of penicillin, q(pen) (units per milligram of dry weight per hour) was independent of specific growth rate over the range 0.014 to 0.086 hr. growth was stopped by restricting the glucose supply to the "maintenance ration," that is, the glucose requirement of the organism at zero growth rate with all other nutrients in excess. ... | 1967 | 16349736 |
penicillin acyltransferase in penicillium chrysogenum. | isotopic exchange of (35)s between penicillins and 6-amino-penicillanic acid (6-apa) was observed in cell-free extracts of penicillium chrysogenum. sulfhydryl-containing compounds were required for activity. dithiothreitol, dithioerythritol, mercaptoethanol, and glutathione served as activators. the acyltransferase was purified threefold by adsorption on calcium phosphate gel at ph 6 and elution at ph 8. the partially purified enzyme showed maximal activity at ph 8. the enzyme was stable at 25 c ... | 1967 | 4964480 |
