Mutations in twenty-eight tryptophan mutants of S. coelicolor A3(2) were mapped relative to the nearest flanking markers. Mutants lacking single enzymatic activities for phosphoribosyltransferase, phosphoribosylanthranilate isomerase, indodeglycerol phosphate synthase, tryptophan synthase A and tryptophan synthase B were identified.
