Complete Genome Sequences of Two Acetylene-Fermenting Pelobacter acetylenicus Strains

Complete Genome Sequence of the Acetylene-Fermenting Pelobacter sp. Strain SFB93

Acetylene fermentation is a rare metabolism that was previously reported as being unique to Pelobacter acetylenicus Here, we report the genome sequence of Pelobacter sp. strain SFB93, an acetylene-fermenting bacterium isolated from sediments collected in San Francisco Bay, CA.

Structural aspects of molybdenum-transhydroxylase from Pelobacter acidigallici and tungsten-acetylene hydratase from Pelobacter acetylenicus

Tungsten-acetylene hydratase from Pelobacter acetylenicus and molybdenum-transhydroxylase from Pelobacter acidigallici: Two novel molybdopterin and iron-sulfur containing enzymes

Acetylene degradation by new isolates of aerobic bacteria and comparison of acetylene hydratase enzymes.

Aerobic acetylene-degrading bacteria were isolated from soil samples. Two isolates were assigned to the species Rhodococcus opacus, two others to Rhodococcus ruber and Gordona sp. They were compared with known strains of aerobic acetylene-, cyanide-, or nitrile-utilizing bacteria. The acetylene hydratases of R opacus could be measured in cell-free extracts only in the presence of a strong reduc...

Purification and characterization of acetylene hydratase of Pelobacter acetylenicus, a tungsten iron-sulfur protein.

Acetylene hydratase of the mesophilic fermenting bacterium Pelobacter acetylenicus catalyzes the hydration of acetylene to acetaldehyde. Growth of P. acetylenicus with acetylene and specific acetylene hydratase activity depended on tungstate or, to a lower degree, molybdate supply in the medium. The specific enzyme activity in cell extract was highest after growth in the presence of tungstate. ...
