CDC group IV c-2: a new Ralstonia species close to Ralstonia eutropha.
CDC group IV c-2, an environmental gram-negative bacillus recently proposed for inclusion in the genus Ralstonia, has been isolated in several human infections. Biochemical characterization and 16S ribosomal DNA (rDNA) sequencing with phylogenetic analysis were used to characterize eight clinical isolates and four type strains. Other typing tools, such as pulsed-field gel electrophoresis (PFGE)...

متن کاملThe hydrogen-sensing apparatus in Ralstonia eutropha.
Molecular hydrogen is widely used by microorganisms as a source of energy. One of the best studied aerobic hydrogen oxidizers, the beta-proteobacterium Ralstonia eutropha (formerly Alcaligenes eutrophus), harbors two distinct [NiFe]-hydrogenases which catalyze the heterolytic cleavage of H2 into 2H+ and 2e-. The genes encoding the hydrogenase subunits are arranged in two large operons together ...
متن کاملThe glyoxylate bypass of Ralstonia eutropha.
The glyoxylate bypass genes aceA1 (isocitrate lyase 1, ICL1), aceA2 (isocitrate lyase 2, ICL2) and aceB1 (malate synthase, MS1) of Ralstonia eutropha HF39 were cloned, sequenced and functionally expressed in Escherichia coli. Interposon-mutants of all three genes (DeltaaceA1, DeltaaceA2 and DeltaaceB1) were constructed, and the phenotypes of the respective mutants were investigated. Whereas R. ...
متن کاملA putative monofunctional glycosyltransferase is expressed in Ralstonia eutropha.
A gene, mgt, encoding a protein homologous to the N-terminal module of class A high-molecular-mass penicillin-binding proteins was identified in Ralstonia eutropha. By using specific antibodies, the corresponding Mgt protein was detected in association with the membrane, confirming that the N-terminal hydrophobic segment functioned as a membrane anchor. A derivative in which the hydrophobic seq...
