| autolysis of bacillus cereus cell walls and isolation of structural components. | autolysis of bacillus cereus n.r.r.l. 569 cell walls was accompanied by hydrolysis of the majority of the 4-o-beta-n-acetylglucosaminyl-n-acetylmuramic acid linkages in mucopeptide, presumably by an endo-beta-n-acetylglucosaminidase. hydrolysis of the n-acetylmuramyl-l-alanine linkages by an amidase also occurred. free d-alanine residues were detected in isolated cell walls and the proportion of these residues increased during autolysis, presumably due to d-alanine carboxypeptidase action. fract ... | 1971 | 5000275 |

| comparison of bacillus cereus bacteriophages cp-51 and cp-53. | transducing bacteriophages cp-51 and cp-53 were compared. unlike cp-51, cp-53 appeared to be a lysogenizing phage. cp-51 gave greater frequencies of co-transduction for linked markers than did cp-53. cp-51 was found to be a larger phage which carried more deoxyribonucleic acid (dna) than cp-53. cp-51 dna contained about 43% guanine plus cytosine and in addition contained 5-hydroxymethyluracil in place of thymine. cp-53 dna contained no unusual bases; its guanine plus cytosine content was 37%. | 1971 | 5000543 |

| in vivo and in vitro action of new antibiotics interfering with the utilization of n-acetyl-glucosamine-n-acetyl-muramyl-pentapeptide. | recent literature on the antibiotics enduracidin, moenomycin, prasinomycin, and 11.837 rp suggested an interaction with murein synthesis. incubation of sensitive strains from bacillus cereus and staphylococcus aureus in a "wall medium" containing labeled l-alanine showed that all four antibiotics inhibited the incorporation of alanine into murein and gave rise to accumulation of radioactive uridine diphosphate-n-acetyl-muramyl (udp-murnac)-pentapeptide. peptidoglycan was synthesized when the par ... | 1971 | 5001198 |
| microstructure of colonies of rod-shaped bacteria. | whole colonies of bacillus cereus, b. megaterium, b. mycoides cn2495, corynebacterium hofmanni nctc1938, escherichia coli, lactobacillus acidophilus ncib1899, nocardia graminis nctc4728, pseudomonas viscosa, and serratia marcescens were prepared for scanning electron microscopic examination by freeze-drying and metal-coating. the arrangement of individual cells within colonies could be seen. cells of bacillus colonies tended to be longer than in liquid culture and irregular in shape and to give ... | 1971 | 5001203 |

| structural studies of fc receptors. v. effect of phospholipase c treatment on the binding activities of the fc receptor of macrophage or its isolated plasma membrane. | the effect of phospholipase c treatment on the binding activity of the fc receptor of guinea pig macrophage was studied to analyze the interaction of the fc receptor with membrane phospholipids necessary for the activity. it was confirmed by subcellular fractionation that the receptor is localized on the plasma membrane. treatment of the whole cell or isolated plasma membrane with phospholipase c of clostridium perfringens diminished the binding of soluble igg2-immune complex to fc receptors on ... | 1984 | 6088472 |
| steroidogenic effect of exogenous phospholipase c on bovine adrenal fasciculata cells. | phospholipase c (bacillus cereus) added to the incubation medium stimulated the steroidogenic activity of bovine adrenal zona fasciculata cell suspensions to a level similar to that induced by optimal concentration of acth. this effect was not related to an increase of cyclic amp; it was calcium-dependent and was also induced by an other bacterial phospholipase c (from clostridium perfringens) whereas phospholipases a2 and d were ineffective. phospholipid metabolism was examined in these cells a ... | 1984 | 6089796 |
| evidence for the role of calcium and diacylglycerol as dual second messengers in thyrotropin-releasing hormone action: involvement of diacylglycerol. | trh stimulates the secretion of prl by clonal gh3 pituitary cells. the studies of the accompanying paper have shown that the secretory response during the first 30-60 min is biphasic (phase i, 0-3 min; phase ii, 5-60 min) and that the phase i response may be mediated through mechanisms involving ca+2 translocation. in previous studies, it has been shown that trh treatment rapidly induces the breakdown of inositol phospholipids with accompanying diacylglycerol accumulation. in this paper, we pres ... | 1984 | 6090104 |

| dna-dependent atpase ii from bacillus cereus. | a new dna-dependent atpase been purified close to homogeneity from soluble extracts of bacillus cereus. this enzyme, called atpase ii catalyses the hydrolysis of atp in the presence of mg2+ or ca2+ and dna. single-stranded linear dna is a cofactor about 3-fold more effective than double-stranded dna. the enzyme catalyses the strand separation of duplex dna in the presence of atp. however, at concentrations higher than 0.5 mm, phosphohydrolysis can occur without concomitant dna unwinding. the enz ... | 1980 | 6107127 |
| the structure of beta-lactamases. | the beta-lactamases are widely distributed in both gram-positive and gram-negative bacteria. they all inactivate penicillins and cephalosporins by opening the beta-lactam ring. many varieties of the enzyme can be distinguished on the basis of their catalytic and molecular properties, but only amino acid sequence determination gives information upon which a molecular phylogeny can be based. the present evidence suggests that the beta-lactamases have a polyphyletic origin. all the beta-lactamases ... | 1980 | 6109327 |
| active sites of beta-lactamases from bacillus cereus. | there are two extracellular beta-lactamases produced by bacillus cereus 569. one of these enzymes, beta-lactamase i, is inactivated by 6-beta-bromopenicillanic acid: the site of reaction is serine-44. this is a conserved amino acid residue in the other beta-lactamases whose structures have been determined, and it becomes a good candidate for an active-site group in these enzymes. the inactivation may involve a rearrangement leading to a dihydrothiazine. the other extracellular enzyme produced by ... | 1980 | 6109328 |
| isolation and properties of pili from spores of bacillus cereus. | structures whose morphology is identical to that of bacterial pili have been isolated from spores of bacillus cereus. the structures are absent from log-phase and sporulating cells. the pili are 6.8 nm in diameter, are of variable length, and appear to emanate randomly from the exosporium. examination of spores from 12 bacillus species showed that only those from b. cereus and b. thuringiensis have pili. although isolated spore pili were shown to be composed of protein, their subunit nature was ... | 1981 | 6109707 |

| specificity of translation of spore polypeptides in bacillus in vitro systems. | cell free extracts prepared from exponentially growing escherichia coli and bacillus cereus as well as from bacillus cereus at the end of exponential growth were optimized for various factors required for amino acid incorporation when programmed with bacillus ribonucleic acid. all three preparations synthesized glutamine synthetase antigen when ribonucleic acid from a bacillus subtilis strain that overproduces glutamine synthetase was added. the post exponential bacillus cereus extract, however, ... | 1981 | 6165330 |
| evidence for the presence of subpopulations of arenicola marina coelomocytes identified by their selective response towards gram+ve and gram-ve bacteria. | in arenicola marina (l.), in vitro attachment and phagocytosis of bacteria appears to be serum-independent and thus, non-specific. mixtures of gram+ve and gram-ve bacterial species (gram+ve/-ve, of two gram+ve (gram+ve/+ve) and of two gram-ve bacterial species (gram-ve/-ve)were overlaid on coelomocyte monolayers, in order to introduce competition for cell surface 'receptors'. an enhanced total phagocytosis was only recorded in the gram+ve/-ve mixtures in comparison with their controls. the resul ... | 1982 | 6175542 |
