| mechanism of action of bacitracin: complexation with metal ion and c 55 -isoprenyl pyrophosphate. | the inhibition by bacitracin of the enzymatic dephosphorylation of c(55)-isoprenyl pyrophosphate is abolished by the addition of chelating agents. if, however, the chelating agent is added after a preincubation of bacitracin with a divalent cation and the lipid substrate, then its addition has little effect, indicating that bacitracin, metal ion, and c(55)-isoprenyl pyrophosphate form a complex. various divalent cations can participate in complex formation, but monovalent cations are ineffective ... | 1971 | 4332017 |

| morphokinetic reaction of streptococcus faecalis (atcc 9790) cells to the specific inhibition of macromolecular synthesis: nucleoid condensation on the inhibition of protein synthesis. | in glutaraldehyde-prefixed exponential-phase cells of streptococcus faecalis the nucleoid is "frozen" in a dispersed configuration. exposure of exponential-phase cells to threonine starvation or to antibiotics inhibiting protein synthesis resulted in progressive condensation of nucleoid fibrils producing an expanding central nucleoid zone or pool. the condensation of the nucleoid was observed to occur at a rate directly proportional to the rate of inhibition of protein synthesis. however, the ex ... | 1972 | 4110925 |
| morphokinetic reaction of cells of streptococcus faecalis (atcc 9790) to specific inhibition of macromolecular synthesis: dependence of mesosome growth on deoxyribonucleic acid synthesis. | the application of quantitative electron microscopy to thin sections of cells of streptococcus faecalis specifically inhibited for deoxyribonucleic acid (dna), ribonucleic acid, and protein synthesis shows that septal mesosomes (i) increase in size when protein synthesis is inhibited by at least 80% while dna synthesis proceeds at no less than 50% of the control rate and (ii) decrease in size when dna synthesis is inhibited 50% or more during the initial 10 min of treatment. this indicates that ... | 1972 | 4110926 |
| some properties of two autolytic-defective mutants of streptococcus faecalis atcc 9790. | the isolation and some properties of two mutants of streptococcus faecalis atcc 9790 (s. faecium) which autolyze at a much slower rate than the wild type are described. compared with the wild type, mutant e71 autolyzed more slowly, contained less active but more latent autolysin in the isolated wall fraction, and possessed a wall of very similar chemical composition and degree of cross-bridging. ultrastructural studies of exponential phase cells showed that cells of e71 were on the average sligh ... | 1972 | 4109890 |

| influence of macromolecular biosynthesis on cellular autolysis in streptococcus faecalis. | the addition of several different antibiotics to growing cultures of streptococcus faecalis, atcc 9790, was found to inhibit autolysis of cells in sodium phosphate buffer. when added to exponential-phase cultures, mitomycin c (0.4 mug/ml) or phenethyl alcohol (3 mg/ml) inhibited deoxyribonucleic acid synthesis, but did not appreciably affect the rate of cellular autolysis. addition of chloramphenicol (10 mug/ml), tetracycline (0.5 mug/ml), puromycin (25 mug/ml), or 5-azacytidine (5 mug/ml) to ex ... | 1972 | 4116754 |
| serum proteins of gnotobiotic rats. | cellulose-acetate and agar gel immunoelectrophoresis were used to study the serum protein patterns of germfree rats before and after monoassociation with a pure culture of staphylococcus aureus (phage type 80/81), streptococcus faecalis, lactobacillus acidophilus, bacteroides fragilis, pseudomonas aeruginosa, or proteus vulgaris. all six bacteria quickly established themselves in the gastrointestinal tract of the germfree rat, and all six increased the animals' total serum proteins. only s. aure ... | 1972 | 4120245 |

| phagocytosis of microbial l-forms. | little data are available regarding l-form phagocyte interactions. due to difficulty with more conventional methods, a serum-free technique of surface phagocytosis employing cellulose ester micropore filters, fluorochrome staining, and reflecting fluorescence microscopy was developed. intracellular localization of l-frms was confirmed by electron microscopy. in timed experiments, phagocytosis of a group d streptococcus (atcc 23241) and its l-form (t53i) were maximal at 30 min, although the bacte ... | 1972 | 4628960 |

| induction and regulation of a nicotinamide adenine dinucleotide-specific 6-phosphogluconate dehydrogenase in streptococcus faecalis. | streptococcus faecalis grown with glucose as the primary energy source contains a single, nicotinamide adenine dinucleotide phosphate (nadp)-specific 6-phosphogluconate dehydrogenase. extracts of gluconate-adapted cells, however, exhibited 6-phosphogluconate dehydrogenase activity with either nadp or nicotinamide adenine dinucleotide (nad). this was shown to be due to the presence of separate enzymes in gluconate-adapted cells. although both enzymes catalyzed the oxidative decarboxylation of 6-p ... | 1972 | 4400413 |

| function of various intestinal bacteria in converting germfree mice to the normal state. | earlier work had shown that a collection of anaerobic bacteria, in conjunction with facultative anaerobes, may be implanted into germfree mice, thereby rendering the animals "normal" with respect to a variety of parameters tested. the present experiments indicate that a different collection of anaerobic bacteria, isolated from the cecum of normal mice, was necessary to convert germfree mice to the "normal" state when the animals were fed a crude diet, rather than the refined food which had been ... | 1972 | 4631910 |
| experimental shigella infections in laboratory animals. i. antagonism by human normal flora components in gnotobiotic mice. | germfree mice were associated with selected species of human intestinal bacteria and then challenged with a streptomycin-resistant shigella flexneri strain. antagonism against shigella was most pronounced in mice associated with escherichia coli and least pronounced in mice associated with bacteroides fragilis. a moderate degree of antagonism could be demonstrated in mice associated with either streptococcus faecalis or bifidobacterium adolescentis. shigella persisted in the cecal contents of e. ... | 1972 | 4631914 |
| growth of streptococcus faecium in the presence of lysozyme. | streptococcus faecium can grow normally in the presence of lysozyme, despite the observation that cell suspensions of the organism are lysed readily by the enzyme. growth in the presence of lysozyme is not due to resistant cells, and the culture is lysed after growth if the ph of the medium is not allowed to drop too low for lysozyme activity. growth followed by lysis in the presence of lysozyme was not exhibited by other organisms tested which were either significantly more resistant or more se ... | 1972 | 4631915 |

| transport of lysine and hydroxylysine in streptococcus faecalis. | data are presented which support the view that l-lysine is transported by two systems in streptococcus faecalis. the system with the higher affinity for l-lysine appears to be specific for l-lysine among the common amino acids and to require an energy source. the second system transports both l-lysine and l-arginine and does not appear to require an energy source. both of these systems will accept hydroxy-l-lysine as a substrate as shown by the energy requirement for hydroxy-l-lysine transport a ... | 1972 | 4621625 |
| fermentation of agmatine in streptococcus faecalis: occurrence of putrescine transcarbamoylase. | putrescine transcarbamoylase, ec 2.1.3.x (carbamoylphosphate:putrescine transcarbamoylase), has been purified from streptococcus faecalis 10c1 grown on agmatine as primary energy source. the formation of n-carbamoylputrescine from putrescine and carbamoylphosphate serves as a convenient and sensitive assay for this enzymatic activity. the enzyme catalyzes both the phosphorolysis arsenolysis of n-carbamoylputrescine. arginine does not induce the synthesis of putrescine transcarbamoylase in s. fae ... | 1972 | 4621632 |
