Asparagine-oxo-acid transaminase

In enzymology, an asparagine-oxo-acid transaminase is an enzyme that catalyzes the chemical reaction


 * L-asparagine + a 2-oxo acid $$\rightleftharpoons$$ 2-oxosuccinamate + an amino acid

Thus, the two substrates of this enzyme are L-asparagine and 2-oxo acid, whereas its two products are 2-oxosuccinamate and amino acid.

This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is L-asparagine:2-oxo-acid aminotransferase. This enzyme is also called asparagine-keto acid aminotransferase. This enzyme participates in alanine and aspartate metabolism and tetracycline biosynthesis. It employs one cofactor, pyridoxal phosphate.
