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 22.214.171.124, 2,4-diaminopentanoate dehydrogenase).
