The acetate kinase of Clostridum acetobutylicum strain P262.

F Diez-Gonzalez1, J B Russell, J B Hunter.   

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 Km for acetate of 160 mM, and a kcat 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.
