Complete genome sequence and analysis of Wolinella succinogenes.
To understand the origin and emergence of pathogenic bacteria, knowledge of the genetic inventory from their nonpathogenic relatives is a prerequisite. Therefore, the 2.11-megabase genome sequence of Wolinella succinogenes, which is closely related to the pathogenic bacteria Helicobacter pylori and Campylobacter jejuni, was determined. Despite being considered nonpathogenic to its bovine host, ...
متن کاملTransport of C(4)-dicarboxylates in Wolinella succinogenes.
C(4)-dicarboxylate transport is a prerequisite for anaerobic respiration with fumarate in Wolinella succinogenes, since the substrate site of fumarate reductase is oriented towards the cytoplasmic side of the membrane. W. succinogenes was found to transport C(4)-dicarboxylates (fumarate, succinate, malate, and aspartate) across the cytoplasmic membrane by antiport and uniport mechanisms. The el...
متن کاملCharacterization of the menaquinone reduction site in the diheme cytochrome b membrane anchor of Wolinella succinogenes NiFe-hydrogenase.
The majority of bacterial membrane-bound NiFe-hydrogenases and formate dehydrogenases have homologous membrane-integral cytochrome b subunits. The prototypic NiFe-hydrogenase of Wolinella succinogenes (HydABC complex) catalyzes H2 oxidation by menaquinone during anaerobic respiration and contains a membrane-integral cytochrome b subunit (HydC) that carries the menaquinone reduction site. Using ...
متن کاملThe purification and some equilibrium properties of the nitrite reductase of the bacterium Wolinella succinogenes.
The bacterium Wolinella succinogenes produces a nitrite reductase enzyme that can be purified to homogeneity in high yield by a combination of detergent extraction, hydroxyapatite chromatography and Mr fractionation. Nitrite reductase activity is found to be present in both a high- and a low-Mr fraction. The high-Mr fraction has been shown to consist of the low-Mr nitrite reductase enzyme assoc...
متن کاملElectron paramagnetic resonance observations on the cytochrome c-containing nitrous oxide reductase from Wolinella succinogenes.
Nitrous oxide reductase from Wolinella succinogenes, an enzyme containing one heme c and four Cu atoms/subunit of Mr = 88,000, was studied by electron paramagnetic resonance (EPR) at 9.2 GHz from 6 to 80 K. In the oxidized state, low spin ferric cytochrome c was observed with gz = 3.10 and an axial Cu resonance was observed with g parallel = 2.17 and g perpendicular = 2.035. No signals were det...
