Abstract Clostridum acetobutylicum strain P262 fermented glucose, pyruvate, or lactate, and the butyrate production was substrate-dependent. Differences in butyrate yield could not be explained by changes in butyrate kinase activities, but the butyrate production was inversely related to acetate kinase activity. The acetate kinase had a pH optimum of 8.0, a K m for acetate of 160 mM, and a k cat of 16,800 min–1. The enyzme had a native molecular mass of 78 kDa; the size of 42 kDa on SDS-PAGE indicated that the acetate kinase of strain P262 was a homodimer.
