Tryptophan synthase (indole-salvaging) (EC 4.2.1.122, tryptophan synthase beta2) is an enzyme with systematic name L-serine hydro-lyase (adding indole, L-tryptophan-forming).[1] This enzyme catalyses the following chemical reaction

L-serine + indole [math]\displaystyle{ \rightleftharpoons }[/math] L-tryptophan + H2O

This enzyme salvages the lost indole to L-tryptophan.
