In enzymology, a 2-aminoethylphosphonate—pyruvate transaminase (EC 2.6.1.37) is an enzyme that catalyzes the chemical reaction

(2-aminoethyl)phosphonate + pyruvate $\rightleftharpoons$ 2-phosphonoacetaldehyde + L-alanine

Thus, the two substrates of this enzyme are (2-aminoethyl)phosphonate and pyruvate, whereas its two products are 2-phosphonoacetaldehyde and L-alanine.

This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is (2-aminoethyl)phosphonate:pyruvate aminotransferase. Other names in common use include (2-aminoethyl)phosphonate transaminase, (2-aminoethyl)phosphonate aminotransferase, (2-aminoethyl)phosphonic acid aminotransferase, 2-aminoethylphosphonate-pyruvate aminotransferase, 2-aminoethylphosphonate aminotransferase, 2-aminoethylphosphonate transaminase, AEP transaminase, and AEPT. This enzyme participates in aminophosphonate metabolism. It employs one cofactor, pyridoxal phosphate.
