Domain Context

CATH Clusters

Superfamily	Type I PLP-dependent aspartate aminotransferase-like (Major domain)
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.
