ID 1.1.1.433 DE sulfoacetaldehyde reductase (NADH). CA 2-hydroxyethane-1-sulfonate + NAD(+) = H(+) + NADH + sulfoacetaldehyde. CC -!- The enzymes from the bacteria Bilophila wadsworthia and Clostridium CC sp. MSTE9 catalyze the reaction only in the reduction direction. CC -!- In the bacterium Bifidobacterium kashiwanohense the optimal reaction CC pH for sulfoacetaldehyde reduction is 7.5, while that for isethionate CC oxidation is 10.0. cf. EC 1.1.1.313.
