Thus, the two substrates of this enzyme are L-lysine and pyruvate, whereas its two products are L-2-aminoadipate 6-semialdehyde 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 L-lysine:pyruvate aminotransferase. Other names in common use include lysine-pyruvate aminotransferase, and Lys-AT.
