PDB structures

L-aspartate + H₂O + O₂

\rightleftharpoons

oxaloacetate + NH₃ + H₂O₂

The 3 substrates of this enzyme are L-aspartate, H₂O, and O₂, whereas its 3 products are oxaloacetate, NH₃, and H₂O₂.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with oxygen as acceptor. The systematic name of this enzyme class is L-aspartate:oxygen oxidoreductase (deaminating). This enzyme participates in alanine and aspartate metabolism and nicotinate and nicotinamide metabolism. It employs one cofactor, FAD.

Structural studies

As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1J5P, 1KNP, and 1KNR.
