ID   4.1.99.1
DE   tryptophanase.
AN   L-tryptophan indole-lyase.
AN   TNase.
CA   H2O + L-tryptophan = indole + NH4(+) + pyruvate.
CC   -!- The enzyme cleaves a carbon-carbon bond, releasing indole and an
CC       unstable enamine product that tautomerizes to an imine form, which
CC       undergoes a hydrolytic deamination to form pyruvate and ammonia.
CC   -!- The latter reaction, which can occur spontaneously, can also be
CC       catalyzed by EC 3.5.99.10.
CC   -!- Also catalyzes 2,3-elimination and beta-replacement reactions of some
CC       indole-substituted tryptophan analogs of L-cysteine, L-serine and
CC       other 3-substituted amino acids.
