Bacillus subtilis IAM1247 had two modification and restriction systems (Bsu1247I and Bsu1247II), the former producing an isoschizomer of PstI endonuclease. A transformant clone was isolated which had Bsu 168, BsuR, and Bsu1247I systems coexisting within a genome.
枯草芽孢杆菌IAM1247有两个甲基化和限制系统(Bsu1247I和Bsu1247II),前者产生PstI核酸内切酶的同裂酶。分离出一个转化体克隆,其基因组中同时存在Bsu 168、BsuR和Bsu1247I系统。
