Protein attributes

Sequence length	266 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Specifically catalyzes the NAD or NADP-dependent dehydrogenation of L-aspartate to iminoaspartate By similarity.
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 By similarity.
Sequence similarities	Belongs to the L-aspartate dehydrogenase family.
