We used strains carrying specific lacZ alleles to identify a new mutator locus in Escherichia coli which generates only G.C----T.A transversions among base substitutions. The locus, mutM, mapped near the cysE locus, which is at 81 min on the genetic map.
我们使用携带特定lacZ等位基因的菌株来鉴定大肠杆菌中的一个新的突变基因座,该基因座在碱基替换中仅产生G.C向T.A的颠换。该基因座mutM定位于cysE基因座附近,在遗传图谱上位于81分钟处。
