Methionine transaminase (EC 2.6.1.88, methionine-oxo-acid transaminase) is an enzyme with systematic name L-methionine:2-oxo-acid aminotransferase.[1][2][3] This enzyme catalyses the following chemical reaction

L-methionine + 2-oxo carboxylate [math]\displaystyle{ \rightleftharpoons }[/math] 2-oxo-4-methylthiobutanoate + L-amino acid

The enzyme is most active with L-methionine.
