| crystal formation by a ribonucleic acid polymerase mutant of bacillus subtilis. | a crystalline inclusion has been observed in a ribonucleic acid polymerase mutant of bacillus subtilis which is conditionally temperature sensitive only during sporulation. the crystal is formed at the permissive temperature in 1 to 2% of the sporulating (stage iii-iv) cells; about 85% of the cells sporulate normally, while the cells with crystals do not sporulate. the wild type does not form crystals at either the permissive (30 c) or the nonpermissive (47 c) temperatures. the crystal may resul ... | 1973 | 4126822 |

| characterization of bleomycin-resistant dna. | after reaction of dna with high concentrations of bleomycin, approximately 80% of the dna becomes trichloroacetic acid (tca) soluble. the remaining 20% of the dna remains tca insoluble. upon further treatment of this tca-insoluble material with high concentrations of the drug, no further drug action can be detected. drug action is defined as fragmentation of dna to smaller molecular size, release of free bases, and tca solubilization. this material which is not attacked by bleomycin has been ter ... | 1973 | 4128368 |

| on the amino-acid sequence of flagellin from bacillus subtilis 168: comparison with other bacterial flagellins. | a partial amino-acid sequence of bacillus subtilis 168 flagellin is presented. the region of unassigned sequence in this 304-residue polypeptide chain spans residues 158-173. comparison of the 27-residue aminoterminal cnbr peptide of b. subtilis 168 flagellin with that derived from the flagellin of the serologically unrelated strain of b. subtilis, w23, shows only three conservative substitutions, whereas the 16-residue carboxyl-terminal peptides derived from these flagellins were identical. the ... | 1973 | 4202846 |
| the occurrence of two types of synthesis of deoxyribonucleic acid during normal growth in bacillus subtilis. | a study of the relative utilization of thymine and thymidine as precursors for dna synthesis during normal growth in bacillus subtilis showed that thymine serves preferentially as a precursor for ;repair' synthesis, whereas thymidine is used preferentially for ;replicative' synthesis. further, evidence was obtained which suggests that during normal growth both ;replicative' and ;repair' dna syntheses occur simultaneously. ;repair' synthesis is distinguished not only on the basis of its preferent ... | 1973 | 4202939 |
| the structure of a polymer containing galactosamine from walls of bacillus subtilis 168. | cell walls of bacillus subtilis 168 contain a phosphorylated polysaccharide composed of n-acetylgalactosamine, glucose and phosphate. controlled acid hydrolysis gives 3-o-beta-d-glucopyranosyl-n-acetylgalactosamine with a phosphomonoester group at the 6-position of glucose. it is likely that the polysaccharide consists of disaccharide units connected by phosphodiester residues joining the 1-position of n-acetylgalactosamine to the 6-position of glucose in the neighbouring unit. | 1973 | 4202940 |

| synthesis of the unusual dna of bacillus subtilis bacteriophage sp-15. | cultures of bacillus subtilis infected with phage sp-15 were examined to investigate the metabolic origin of two of the unique components of the phage dna: the component responsible for the unusually high buoyant density in cscl and the unusual pyrimidine, 5-(4', 5'-dihydroxypentyl) uracil (dhpu). newly synthesized pulse-labeled dna was light in buoyant density and shifted to the high density of mature phage dna upon further incubation. parental dna was converted to a light-density intermediate ... | 1973 | 4203083 |
| viral protein synthesis in bacteriophage phi 29-infected bacillus subtilis. | twenty-three (14)c-labeled phage phi29-specific proteins in lysates of uv-irradiated bacillus subtilis have been resolved by sodium dodecyl sulfate polyacrylamide gel electrophoresis and identified by autoradiography. included in this group of proteins are the six major structural proteins of the virion. analysis of the temporal sequence of viral protein synthesis indicates that three groups of proteins can be identified by time of appearance, beginning at 2 to 4, 4 to 6, or 8 to 10 min after in ... | 1973 | 4203085 |

| pleiotropic menaquinone-deficient mutant of bacillus subtilis. | a multiple aromatic amino acid auxotroph of bacillus subtilis 168 has been isolated which is unable to synthesize menaquinone-7 (mk-7) unless supplied with shikimic acid (shk). the mutant, rb163, was isolated by selecting for resistance to low levels (1.5 mug/ml) of kanamycin. enzymatic and genetic analyses show that the strain is an arod mutant lacking 5-dehydroshikimate reductase. under growth conditions in which its mk-7 deficiency is expressed, rb163 is deficient in cytochromes a, b, and c, ... | 1973 | 4199502 |
| phenotypes of pleiotropic-negative sporulation mutants of bacillus subtilis. | the phenotypic properties of representatives of the five genetic classes of pleiotropic-negative sporulation mutants have been investigated. protease production, alkaline and neutral proteases, was curtailed in spoa mutants, but the remainder of mutant classes produced both proteases, albeit at reduced levels. the spoa and spob mutants plaqued phi2 and phi15 at high efficiency, but the efficiency of plating of these phages on spoe, spof, and spoh mutants was drastically reduced. antibiotic was p ... | 1973 | 4199504 |
| ethidium bromide-resistant mutant of bacillus subtilis. | an ethidium bromide-resistant mutant (eb8) derived from a marburg strain of bacillus subtilis was found to be conditionally resistant to 10 mug of ethidium bromide per ml. expression of resistance is complete only during vegetative growth at incubation temperatures above 30 c in complex medium or minimal medium supplemented with casamino acids. strain eb8 is cross-resistant to acriflavine and proflavine. the ethidium bromide resistance marker is co-transduced with hisa1 at a frequency of 6% and ... | 1973 | 4199505 |
| genetic mapping of a mutant defective in d,l-alanine racemase in bacillus subtilis 168. | genetic analysis of a d-alanine requiring mutant (dal) of bacillus subtilis reveals that the gene that codes for d,l-alanine racemase is linked to purb. the order of genes in this region of the chromosome is purb, pig, tsi, dal. thus there are at least two clusters of genes that regulate cell wall biosynthesis in b. subtilis. | 1973 | 4199510 |
| genetic and biochemical characterization of mutants of bacillus subtilis defective in succinate dehydrogenase. | eleven succinate-accumulating mutants of bacillus subtilis have been mapped by transformation and transduction crosses and characterized with respect to activities of citric acid cycle enzymes. these mutants could be divided into three genetic groups. nine of the mutants were found to map between arga and leu in the citf locus. a second group was located between lys-1 and trpc2 and the third group could not be located on the b. subtilis chromosome in extensive transduction crosses. all of the ci ... | 1973 | 4199512 |
| threonine synthetase-catalyzed conversion of phosphohomoserine to alpha-ketobutyrate in bacillus subtilis. | an enzyme activity of bacillus subtilis has been found that catalyzes the dephosphorylation and deamination of phosphohomoserine to alpha-ketobutyrate, resulting in a bypass of threonine in isoleucine biosynthesis. in crude extracts of a strain deficient in the biosynthetic isoleucine-inhibitable threonine dehydratase, phosphohomoserine was converted to alpha-ketobutyrate. phosphohomoserine conversion to alpha-ketobutyrate was shown not to involve a threonine intermediate. single mutational even ... | 1973 | 4199513 |
