CC   -!- FUNCTION: Specifically catalyzes the NAD or NADP-dependent
CC       dehydrogenation of L-aspartate to iminoaspartate. {ECO:0000255|HAMAP-
CC       Rule:MF_01265}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + L-aspartate + NADP(+) = H(+) + NADPH + NH4(+) +
CC         oxaloacetate; Xref=Rhea:RHEA:11784, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:16452, ChEBI:CHEBI:28938,
CC         ChEBI:CHEBI:29991, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349; EC=1.4.1.21;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01265};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + L-aspartate + NAD(+) = H(+) + NADH + NH4(+) +
CC         oxaloacetate; Xref=Rhea:RHEA:11788, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:16452, ChEBI:CHEBI:28938,
CC         ChEBI:CHEBI:29991, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=1.4.1.21;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01265};
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; iminoaspartate
CC       from L-aspartate (dehydrogenase route): step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_01265}.
CC   -!- MISCELLANEOUS: The iminoaspartate product is unstable in aqueous
CC       solution and can decompose to oxaloacetate and ammonia.
CC       {ECO:0000255|HAMAP-Rule:MF_01265}.
CC   -!- SIMILARITY: Belongs to the L-aspartate dehydrogenase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01265}.
