Indole-Lyase, Tryptophan

L-Tryptophan indole-lyase (deaminating)

Tryptophan Indole Lyase

Tryptophan Indole-Lyase

An enzyme that catalyzes the conversion of L-tryptophan and water to indole, pyruvate, and ammonia. It is a pyridoxal-phosphate protein, requiring K+. It also catalyzes 2,3-elimination and beta-replacement reactions of some indole-substituted tryptophan analogs of L-cysteine, L-serine, and other 3-substituted amino acids.
