Superfamily Aspartate Aminotransferase, domain 1
Functional Family L-tryptophan--pyruvate aminotransferase 1

Enzyme Information

2.6.1.99
L-tryptophan--pyruvate aminotransferase.
based on mapping to UniProt Q9S7N2
L-tryptophan + pyruvate = indole-3-pyruvate + L-alanine.
-!- This plant enzyme, along with EC 1.14.13.168, is responsible for the biosynthesis of the plant hormone indole-3-acetate from L-tryptophan.
2.6.1.27
Tryptophan transaminase.
based on mapping to UniProt Q9S7N2
L-tryptophan + 2-oxoglutarate = (indol-3-yl)pyruvate + L-glutamate.
-!- Also acts on 5-hydroxytryptophan and, to a lesser extent, on the phenyl amino acids.
