Abstract excerpt
The hmc operon of Desulfovibrio vulgaris subsp. vulgaris Hildenborough encodes a transmembrane redox protein complex (the Hmc complex) that has been proposed to catalyze electron transport linking periplasmic hydrogen oxidation to cytoplasmic sulfate reduction. We have replaced a 5-kb DNA fragment containing most of the hmc operon by the cat gene. The resulting chloramphenicol-resistant mutant D. vulgaris H801...
