Tryptophan synthase
WebTryptophan synthase (TrpS) is an α2β2 tetramer participating in the biosynthesis of tryptophan [1]. TrpS α subunit catalyzes the formation of indole and glyceraldehyde-3-phosphate (G3P) from indole-3-glycerol phosphate (IGP). The β subunit catalyzes in a pyridoxal-phosphate (PLP) dependent reaction the formation of tryptophan (Trp) from ...
