ID 1.1.1.309 DE phosphonoacetaldehyde reductase (NADH). CA 2-hydroxyethylphosphonate + NAD(+) = H(+) + NADH + phosphonoacetaldehyde. CC -!- The enzyme from Streptomyces viridochromogenes catalyzes a step in CC the biosynthesis of phosphinothricin tripeptide, the reduction of CC phosphonoacetaldehyde to 2-hydroxyethylphosphonate. CC -!- The preferred cofactor is NADH, lower activity with NADPH. DR D9XF45, PHPC_STRVT ; //
