Protein attributes

Sequence length	266 AA.
Sequence status	Complete.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Specifically catalyzes the NAD or NADP-dependent dehydrogenation of L-aspartate to iminoaspartate By similarity. HAMAP MF_01265
Catalytic activity	L-aspartate + H2O + NAD(P)+ = oxaloacetate + NH3 + NAD(P)H. HAMAP MF_01265
Pathway	Cofactor biosynthesis; NAD(+) biosynthesis; iminoaspartate from L-aspartate (dehydrogenase route): step 1/1. HAMAP MF_01265
Miscellaneous	The iminoaspartate product is unstable in aqueous solution and can decompose to oxaloacetate and ammonia By similarity. HAMAP MF_01265
Sequence similarities	Belongs to the L-aspartate dehydrogenase family.
