physiological role of 70s ribosomes in bacteria.evidence is presented indicating that free 70s ribosomes are real components of bacillus stearothermophilus and escherichia coli in exponential and stationary phases of growth. after pulses of radioactive leucine or uracil were given, protein synthesis was instantaneously stopped by chloramphenicol, or polypeptide growth was allowed to proceed to completion in slowly cooled cells. analysis of label distribution in sucrose gradients showed that 70s monomers, and not subunits, are final products o ...19694894332

influence of oxygen on development of nitrate respiration in bacillus stearothermophilus.a denitrifying mutant of bacillus stearothermophilus nca 2184, strain 2184-d, was used to explore the development of nitrate respiration in relation to oxygen respiration. aerobically grown wild-type cultures could acquire the ability to use nitrate as a result of selection of nitrate-respiring mutants by the presence of nitrate and a reduced oxygen tension. fluctuation analysis has revealed that the frequency of occurrence of the nitrate-respiring mutant is about 7.5 x 10(-8) per bacterium per ...19695788697
cell-free amino acid-incorporating systems from bacillus licheniformis and bacillus stearothermophilus 10.cell-free amino acid-incorporating systems were prepared from log-phase cells of bacillus licheniformis and b. stearothermophilus 10. no differences were observed between the two systems with respect to the types and relative amounts of the ribosomes, the time dependence of incorporation, and the optimal magnesium ion concentration (4 mm). the b. licheniformis system showed greater dependence on added transfer ribonucleic acid (trna) and was less stimulated by polyuridylic acid (poly u) than the ...19695788703

chemical states of bacterial spores: heat resistance and its kinetics at intermediate water activity.bacterial spore heat resistance at intermediate water activity, like aqueous and strictly dry heat resistance, is a property manipulatable by chemical pretreatments of the dormant mature spore. heat resistances differ widely, and survival is prominently nonlogarithmic for both chemical forms of the spore. log survival varies approximately as the cube of time for the resistant state of bacillus stearothermophilus spores and as the square of time for the sensitive state. a method for measuring hea ...19705418938

mode of action of the competence-inducing factor of bacillus stearothermophilus.development of competence in the noncompetent mutant of bacillus stearothermophilus 4s requires a soluble competence-inducing factor (cf). this study describes several observations that define the mechanism of action of this factor. (i) cf interacts with cells, protoplasts, or cytoplasmic membranes in a temperature-dependent reaction; incubation of cf with cells alters the sedimentation properties of the cells. (ii) association between cf and the cytoplasmic membrane appears to be the first and ...19714934067
factors affecting transfection in bacillus stearothermophilus.the conditions for the infection of bacillus stearothermophilus 4s with tp-1c phage deoxyribonucleic acid (dna) are described. cells from log-phase cultures are the most susceptible to phage dna infection (transfection). a cellular component (competence factor) which enhances transfection is released into the culture medium during the transition period between the log and stationary phase of growth. transfection is stimulated in the order of decreasing effectiveness, by fe(3+), mn(2+), and mg(2+ ...19714934070

heat stabilities of ribosomal subunits and reassociated ribosomes from bacillus stearothermophilus.absorbance-temperature profiles reveal that both the 30s and 50s ribosomal subunits from bacillus stearothermophilus are more thermostable than the comparable escherichia coli particles. thermophile ribosomes formed by the reassociation of subunits do not display functional heat stability.19714941572
association factor of ribosomal subunits from bacillus stearothermophilus.the isolation of a new factor, which can cause the in vitro association of 30s and 50s ribosomal subunits at low mg(++) concentration, is described. the association factor is eluted together with the dissociation protein when ribosomes of bacillus stearothermophilus are washed with salt solutions of high concentration. the association activity is heat-stable, whereas dissociation factor is inactivated after 10 min at 80 degrees c. this treatment allows the separation of both factors. several pro ...19714941986

homology of ribosomal ribonucleic acid diverse bacterial species with escherichia coli and bacillus stearothermophilus.hybridization competition experiments were used to examine the ribosomal ribonucleic acid (rrna) homologies of 22 bacteria and 3 higher organisms with escherichia coli and bacillus stearothermophilus. although little or no homology was observed with the higher organisms, the bacteria showed a wide range of homologies. organisms whose rrna showed closer homology to e. coli rrna showed less rrna homology to b. stearothermophilus rrna and vice versa.19714329734

amino acid sequence around the catalytic site in glyceraldehyde-3-phosphate dehydrogenase from bacillus stearothermophilus.the tryptic peptide containing the active-site cysteine in glyceraldehyde-3-phosphate dehydrogenase from bacillus stearothermophilus 1503 was isolated after inhibition of the enzyme with (14)c-iodoacetate. the amino acid sequence of the 20-residue peptide was determined by 19 successive cycles of dansyl-edman degradation. the sequence shows considerable homology with its counterparts from mesophilic sources but differs by the addition of ala-his-his at the n-terminus and by the substitution of p ...197216559157
localization and solubilization of the respiratory nitrate reductase of bacillus stearothermophilus.membranes were isolated from bacillus stearothermophilus 2184d by lysozyme digestion of the cell wall and subsequent differential centrifugation. observations with the electron microscope indicate that such membranes are relatively intact and have a typical membrane appearance. nitrate will preferentially oxidize the cytochrome b of such membranes. approximately 80% of the total respiratory nitrate reductase activity of whole cells can be localized in the washed membrane fraction and the process ...19724333609
physical aggregation and functional reconstitution of solubilized membranes of bacillus stearothermophilus.isolated membranes of bacillus stearothermophilus 2184d can be disrupted by treatment with sodium dodecyl sulfate (sds). this disruption is attended by a decreased turbidity of membrane suspensions and a differential loss of activities of the electron transport system. reduced methyl viologen (mvh)-nitrate reductase activity is insensitive to sds treatment, whereas reduced nicotinamide adenine dinucleotide (nadh)-nitrate reductase and cyanide-sensitive nadh oxidase activities are decreased by 80 ...19724333610
