A physical map of the chromosome of an M type 1 strain of Streptococcus pyogenes was constructed following digestion with three different restriction enzymes, SmaI, SfiI, and SgrAI, and separation and analysis of fragments by pulsed-field gel electrophoresis. The genome size of this strain was estimated to be 1,920 kb. By employing Southern hybridization and PCR analysis, 36 genes were located on the map.
用三种不同的限制性内切酶SmaI、SfiI和SgrAI消化化脓性链球菌M1型菌株的染色体,然后通过脉冲场凝胶电泳分离和分析片段,构建了该菌株的物理图谱。该菌株的基因组大小估计为1920 kb。通过Southern杂交和PCR分析,在图谱上定位了36个基因。
