EC 1.4.1.26

Accepted name: 2,4-diaminopentanoate dehydrogenase (NAD+)

Reaction: (2R,4S)-2,4-diaminopentanoate + H2O + NAD+ = (2R)-2-amino-4-oxopentanoate + NH3 + NADH + H+

Other name(s): DAPDH (ambiguous)

Systematic name: (2R,4S)-2,4-diaminopentanoate:NADP+ oxidoreductase (deaminating)

Comments: The enzyme, characterized from an unknown bacterium in an environmental sample, has some activity with (2R,4R)-2,4-diaminopentanoate. It has very low activity with NADP+ (cf. EC 1.4.1.12, 2,4-diaminopentanoate dehydrogenase).
