| mapping the active site of ribonuclease p rna using a substrate containing a photoaffinity agent. | ribonuclease p rna is the catalytic moiety of the ribonucleoprotein enzyme that removes precursor sequences from 5'-ends of pre-trnas. a photoaffinity cross-linking agent was coupled to the substrate phosphate on which rnase p acts and used to map nucleotides in the vicinity of the catalytic site of this ribozyme. mature trna(phe) containing a 5'-thiophosphate was synthesized by transcription in vitro using phage t7 rna polymerase in the presence of guanosine 5'-phosphorothioate. the photoagent ... | 1990 | 1701142 |
| spectroscopic and ligand-binding properties of an oxygen-binding heme protein from chromatium vinosum. | magnetic circular dichroism spectra were obtained for the oxidized and reduced forms of cyanide, azide and carbon monoxide complexes of an o2-binding hemeprotein isolated from the photosynthetic purple sulfur bacterium, chronatium vinosum. cyanide binding to the protein, which results in formation of a low-spin complex, was highly ph dependent with little complex formation observed at ph values near or below 7. | 1988 | 3355839 |
| lipopolysaccharides of thiocystis violacea, thiocapsa pfennigii, and chromatium tepidum, species of the family chromatiaceae. | the lipopolysaccharides (lps) of three species of purple sulfur bacteria (chromatiaceae), thiocystis violacea, thiocapsa pfennigii, and the moderately thermophilic bacterium chromatium tepidum, were isolated. the lps of thiocystis violacea and chromatium tepidum contained typical o-specific sugars, indicating o-chains. long o-chains were confirmed for these species by sodium deoxycholate gel electrophoresis of their lps. thiocapsa pfennigii, however, had short or no o-chains. the core region of ... | 1988 | 3384808 |
| the primary structure of thioredoxin from chromatium vinosum determined by high-performance tandem mass spectrometry. | the primary structure of thioredoxin, a redox protein isolated from chromatium vinosum, was determined by high-performance tandem mass spectrometry, which permitted sequencing of the 14 peptides (ranging in length from 2 to 18 amino acids) generated by digestion with trypsin and of several peptides produced by staphylococcus aureus protease. the mass spectrometrically determined molecular weights of the peptides from the latter digest were used to properly align the tryptic peptides, which could ... | 1987 | 3567166 |

| temperature and solvent effects on reaction centers from chloroflexus aurantiacus and chromatium tepidum. | temperature and solvent effects on reaction center structures were examined in two thermophilic photosynthetic bacteria, chloroflexus aurantiacus and chromatium tepidum, in order to gain insight into the interactions among the reaction center proteins and pigment systems. thermal stability of the reaction centers was found to be proportional to the optimum growth temperature. circular dichroism (cd) spectra in the 250-300 nm region indicated that thermal denaturation destroyed tertiary structure ... | 1991 | 1778980 |
| bacterial motility: handedness and symmetry. | many bacteria swim by rotating thin helical filaments that extend into the external medium, as with common bacteria, or run beneath the outer membrane, as with spirochetes. each filament is driven at its base by a motor that turns alternately clockwise and counterclockwise. the motor-filament complex is called a flagellum. other kinds of bacteria glide, but their organelles of locomotion are not known. since bacteria are microscopic and live in an aqueous environment, they swim at low reynolds' ... | 1991 | 1802650 |
| magnetic susceptibility of hydrogenase from desulfovibrio vulgaris. | magnetization and magnetic susceptibility measurements revealed that the hydrogenase [ec 1.12.2.1] from desulfovibrio vulgaris miyazaki f has an independent unpaired electron in its iron-sulfur cluster. the paramagnetic center of the desulfovibrio hydrogenase is, therefore, different from that in the chromatium hydrogenase which interacts with another paramagnetic center, probably nickel. | 1985 | 3897216 |

| circular dichroism and redox properties of high redox potential ferredoxins. | the circular dichroism (cd) spectra of 13 examples of high-potential iron-sulfur proteins (hipips), a class of [4fe-4s] ferredoxins, have been determined. in contrast to the proposal of carter [carter, c. w., jr. (1977) j. biol. chem. 252, 7802-7811], no strict correlation between visible cd features and utilization of the [4fe-4s]2+/[4fe-4s]3+ oxidation levels was found. although most hipips have these features, the model requires their presence in all species. there is also no simple relations ... | 1985 | 3925987 |

| rbcr [correction of rcbr], a gene coding for a member of the lysr family of transcriptional regulators, is located upstream of the expressed set of ribulose 1,5-bisphosphate carboxylase/oxygenase genes in the photosynthetic bacterium chromatium vinosum. | an open reading frame, rbcr, was identified 226 bp upstream of rbcab, i.e., the ribulose 1,5-bisphosphate carboxylase genes expressed in the phototrophic purple bacterium chromatium vinosum. several features reveal that rbcr encodes a member of the lysr family of transcriptional regulators, in which an anomalous content of lysine and arginine residues (lys/arg anomaly) was found. the expression of rbcr in escherichia coli as a protein fused to the n-terminal region of beta-galactosidase led to r ... | 1991 | 1907267 |
| effects of ph and exocyclic substitution on flavosemiquinone reactivity with redox proteins and inorganic oxidants. | the effect of ph on the reaction of free flavosemiquinone analogs generated by laser-flash photolysis with oxidized chromatium vinosum high-potential iron-sulfur protein, other iron-containing redox proteins, and nonbiological one-electron oxidants has been investigated. the results demonstrate that the second-order rate constant for the oxidation of lumiflavin flavosemiquinone increases dramatically with increasing ph for the redox proteins and some of the other oxidants. the ph-rate constant p ... | 1985 | 3985626 |

| ligand-controlled dissociation of chromatium vinosum cytochrome c'. | carbon monoxide binding to chromatium vinosum ferrocytochrome c' has been studied by high-precision equilibrium methods. in contrast to the co binding properties of rhodospirillum molischianum cytochrome c' [doyle, m. l., weber, p. c., & gill, s. j. (1985) biochemistry 24, 1987-1991], co binding to c. vinosum cytochrome c' is found to be unusual in the following ways. the binding curve is found to be cooperative with typical hill coefficients equal to 1.25. the shape of the binding curve is asym ... | 1986 | 3013306 |
