UniProt ID: Q66I59
FUNCTION: Specifically catalyzes the NAD or NADP-dependent dehydrogenation of L-aspartate to iminoaspartate. {ECO:0000250}.
CATALYTIC ACTIVITY: L-aspartate + H(2)O + NAD(P)(+) = oxaloacetate + NH(3) + NAD(P)H.
PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; iminoaspartate from L-aspartate (dehydrogenase route): step 1/1.
MISCELLANEOUS: The iminoaspartate product is unstable in aqueous solution and can decompose to oxaloacetate and ammonia. {ECO:0000250}.
SIMILARITY: Belongs to the L-aspartate dehydrogenase family. {ECO:0000305}.
