摘要
Twenty-eight genetic loci have been physically mapped to specific large restriction fragments of the Streptococcus mutans GS-5 chromosome by hybridization with probes of cloned genes or, for transposon-generated amino acid auxotrophs, with probes for Tn916. In addition, restriction fragments generated by one low-frequency-cleavage enzyme were used as probes to identify overlapping fragments generated by other restriction enzymes. The approach allowed construction of a low resolution physical map of the S. mutans GS-5 genome using restriction enzymes ApaI (5'-GGGCC/C), SmaI (5'-CCC/GGG), and NotI (5'-GC/GGCCGC).
