L tryptophan—pyruvate aminotransferase

L-tryptophan---pyruvate aminotransferase (EC 2.6.1.99, TAA1 (gene), vt2 (gene)) is an enzyme with systematic name L-tryptophan:pyruvate aminotransferase. This enzyme catalyses the following chemical reaction

L-tryptophan + pyruvate ⇌ indole-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.
