EC 1.1.1.387     
Accepted name: L-serine 3-dehydrogenase (NAD+)
Reaction: L-serine + NAD+ = 2-aminoacetaldehyde + CO2 + NADH + H+ (overall reaction)
(1a) L-serine + NAD+ = 2-aminomalonate semialdehyde + NADH + H+
(1b) 2-aminomalonate semialdehyde = 2-aminoacetaldehyde + CO2 (spontaneous)
Other name(s): NAD+-dependent L-serine dehydrogenase
Systematic name: L-serine:NAD+ 3-oxidoreductase
Comments: The enzyme, purified from the bacterium Pseudomonas aeruginosa, also shows activity with L-threonine (cf. EC 1.1.1.103, L-threonine 3-dehydrogenase). The enzyme has only very low activity with NADP+ [cf. EC 1.1.1.276, serine 3-dehydrogenase (NADP+)].
