Two mutations restricting the leakiness of an amber mutant are described. They were selected without the use of streptomycin: one maps in the strA region (at 64 minutes of the current E. coli chromosomal map) but is streptomycin sensitive and the other in the threonine region (at the origin of the map), 23% cotransducible with threonine by P1.
描述了两个限制琥珀突变体渗漏性的突变。它们是在不使用链霉素的情况下筛选出来的:一个位于strA区域(在当前大肠杆菌染色体图谱的64分钟处),但对链霉素敏感,另一个位于苏氨酸区域(在图谱的起点),与苏氨酸通过P1共转导的频率为23%。
