| hydrogen bonding of sulfur ligands in blue copper and iron-sulfur proteins: detection by resonance raman spectroscopy. | the resonance raman spectrum of the blue copper protein azurin from alcaligenes denitrificans exhibits nine vibrational modes between 330 and 460 cm-1, seven of which shift 0.4-3.0 cm-1 to lower energy after incubation of the protein in d2o. these deuterium-dependent shifts have been previously ascribed to exchangeable protons on imidazole ligands [nestor, l., larrabee, j. a., woolery, g., reinhammar, b., & spiro, t. g. (1984) biochemistry 23, 1084] or to exchangeable protons on amide groups whi ... | 1987 | 3442645 |
| growth regulation of the b lymphoma cell line wehi-231 by anti-immunoglobulin, lipopolysaccharide, and other bacterial products. | the growth of wehi-231, a murine immature b lymphoma cell line, was inhibited by anti-igm antibodies. the inhibition of proliferation, as measured by [3h]thymidine incorporation, occurred between 16 and 28 hr after addition of anti-igm. moreover, the growth arrest was irreversible: cells that were cultured with anti-igm for 18 hr and then recultured without it failed to recover the ability to proliferate, even though cells treated for up to 30 hr with anti-igm remained viable, as measured by try ... | 1986 | 3489760 |
| induction of human immunoglobulin synthesis (igg, iga) by the novel, t cell independent mitogen cytophaga allerginae endotoxin. | cytophaga allerginae endotoxin (cae) has been purified from c. allerginae, a newly discovered bacterial species isolated from a chilled water spray humidification system. the present study was undertaken in order to determine whether cae can induce immunoglobulin synthesis by human peripheral blood lymphocytes (pbl) in culture. to this end, human pbl were purified and cultured with either pokeweed mitogen at 5 micrograms/ml, or cae (at varying concentrations) for 6 days. the levels of igg and ig ... | 1987 | 3497882 |
| fine structure and host-virus relationship of a marine bacterium and its bacteriophage. | valentine, artrice f. (georgetown university, washington, d.c.), and george b. chapman. fine structure and host-virus relationship of a marine bacterium and its bacteriophage. j. bacteriol. 92:1535-1554. 1966.-the fine structure of a gram-negative marine bacterium, cytophaga marinoflava sp. n., has been revealed by ultrathin sectioning and electron microscopy. stages in the morphogenesis of the bacterial virus ncmb 385, which has been shown to be highly specific for this organism, were also demo ... | 1966 | 5924277 |
| phylogeny of bacteroides, prevotella, and porphyromonas spp. and related bacteria. | the phylogenetic structure of the bacteroides subgroup of the cytophaga-flavobacter-bacteroides (cfb) phylum was examined by 16s rrna sequence comparative analysis. approximately 95% of the 16s rrna sequence was determined for 36 representative strains of species of prevotella, bacteroides, and porphyromonas and related species by a modified sanger sequencing method. a phylogenetic tree was constructed from a corrected distance matrix by the neighbor-joining method, and the reliability of tree b ... | 1994 | 8300528 |

(georgetown university, washington, d.c.), ronald v. citarella, omar salazar, and rita r. colwell. properties of two marine bacteriophages. j. bacteriol. 91:1136-1139. 1966.-various properties have been determined for two bacteriophages, ncmb 384 and 385, and their host, ncmb 397, a cytophaga sp., isolated from the marine environment. the purified bacteriophages have been subjected to serological analysis, results of which indicate a high degree of relatedness. purified, highly po ... | 1966 | 5929746 |
| tan-1057 a-d, new antibiotics with potent antibacterial activity against methicillin-resistant staphylococcus aureus. taxonomy, fermentation and biological activity. | two gram-negative bacteria were found to produce the new antibacterial antibiotics tan-1057 a, b, c and d. the producing bacteria were characterized and designated as flexibacter sp. pk-74 and pk-176. these antibiotics were active against gram-negative and gram-positive bacteria, including methicillin-resistant staphylococcus aureus. tan-1057 a inhibited protein biosynthesis in escherichia coli and s. aureus. it showed excellent protective effects against an experimental methicillin-resistant s. ... | 1993 | 8501003 |
| purification, characterization and specificity of chondroitin lyases and glycuronidase from flavobacterium heparinum. | the chondroitin lyases from flavobacterium heparinum (cytophaga heparinia) have been widely used in depolymerization of glycosaminoglycan and proteoglycan chondroitin sulphates. oligosaccharide products derived from chondroitin sulphate can be further degraded by glycuronidases and sulphatases obtained from the same organism. there has been no reported purification of these enzymes to homogeneity nor is there any information on their physical and kinetic characteristics. the absence of pure enzy ... | 1995 | 8526872 |
| the enzymic degradation of porphyran. | 1. the algal galactan, porphyran, was incubated with enzymes from a cytophaga sp. and the products were examined. 2. only about 30% of the porphyran was recovered in the form of oligosaccharides, the remainder being of high molecular weight. 3. among the saccharides were d-galactose, 6-o-methyl-d-galactose, neoagarobiose, neoagarotetraose and oligosaccharides containing 6-o-methyl-d-galactose, the principal of which has been tentatively identified as 6(3)-o-methyl-neoagarotetraose. fragments con ... | 1967 | 6060448 |
| development of techniques for the genetic manipulation of the gliding bacterium cytophaga johnsonae. | cytophaga johnsonae displays many features that make it an excellent model of bacterial gliding motility. unfortunately, genetic analyses of c. johnsonae, or any related gliding bacteria, were not possible because of a complete lack of selectable markers, cloning vectors, transposons, and convenient methods of gene transfer. as a first step toward a molecular analysis of gliding motility of c. johnsonae, we developed these genetic techniques and tools. common broad-host-range plasmids and transp ... | 1996 | 8550486 |
