}}L-tryptophan—pyruvate aminotransferase ({{EC number|2.6.1.99}}, TAA1 (gene), vt2 (gene)) is an enzyme with systematic name L-tryptophan:pyruvate aminotransferase.[1][2][3][4] This enzyme catalyses the following chemical reaction
L-tryptophan + pyruvateindole-3-pyruvate + L-alanine
This plant enzyme, along with EC 1.14.13.168, indole-3-pyruvate monooxygenase, is responsible for the biosynthesis of the plant hormone indole-3-acetate from L-tryptophan.
