Biochemical pathway of tryptophan biosynthesis. Acronyms that are currently used for the seven monofunctional proteins of Bacillus subtilis are shown in brackets below the acronyms used in this paper. TrpAa, large aminase subunit of anthranilate synthase; TrpAb, small glutamine-binding subunit of anthranilate synthase; TrpB, anthranilate phosphoribosyl transferase; TrpC, phosphoribosyl-anthranilate isomerase; TrpD, indoleglycerol phosphate synthase; TrpEa, α subunit of tryptophan synthase; TrpEb, β subunit of tryptophan synthase.
