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.
将天蓝色链霉菌A3(2)的28个色氨酸突变体中的突变相对于最邻近的侧翼标记进行定位。鉴定出了缺乏磷酸核糖基转移酶、磷酸核糖基邻氨基苯甲酸异构酶、吲哚甘油磷酸合酶、色氨酸合酶A和色氨酸合酶B单一酶活性的突变体。
