In order to mutagenizeStreptococcus mutansa marker rescue plasmid, pVA891, was employed. The plasmid was ligated withSau3AI digested chromosomal DNA fragments fromS. mutansGS-5IS3 and the resultant plasmids were amplified inEscherichia coli. These plasmids were then randomly integrated into the chromosome of strain GS-5IS3 following transformation. Lactose-negative transformants were isolated as white colonies on lactose-BTR-Xgal agar plates containing erythromycin. Six lactose-negative mutants representing three different chromosomal sites of integration were isolated from about eight thousand transformants. Mutant chromosomal DNA fragments flanking the plasmids were recovered by a marker-rescue method inE. coliand exhibited phospho-β-galactosidase activity.
