Tryptophan synthase (indole-salvaging)

Tryptophan synthase (indole-salvaging) (, tryptophan synthase beta2) is an enzyme with systematic name  L -serine hydro-lyase (adding indole, L -tryptophan-forming). This enzyme catalyses the following chemical reaction


 * L -serine + indole $$\rightleftharpoons$$ L -tryptophan + H2O

This enzyme salvages the lost indole to L -tryptophan.
