Accepted name: L-tryptophan ammonia lyase
Reaction: L-tryptophan = 3-indoleacrylate + NH3
Glossary: 3-indoleacrylate = (2E)-3-(1H-indol-3-yl)prop-2-enoate
Other name(s): WAL
Systematic name: L-tryptophan ammonia-lyase (3-indoleacrylate-forming)
Comments: The enzyme, characterized from the bacterium Rubrivivax benzoatilyticus JA2, requires no cofactors. It acts on L-phenylalanine and L-glutamate with about 60% of the activity with L-tryptophan, and on L-tyrosine, glycine, and L-alanine with about 30% of the activity.
