| Abstract: | Membrane vesicles of Clostridium thermoautotrophicum prepared by osmotic lysis after lysozyme treatment contained carbon monoxide dehydrogenase and methylenetetrahydrofolate dehydrogenase with specific activities three- to fourfold higher than the specific activity of the cytoplasm. The membrane-associated carbon monoxide dehydrogenase mediated the reduction with CO or the oxidation with CO2 of b-type cytochromes and other electron carriers in the membrane. |
