Three genes coding for the endonuclease, methylase, and specificity subunits of a type I restriction-modification (R-M) system in the Lactococcus lactis plasmid pIL2614 have been characterized. Plasmid location, sequence homologies, and inactivation studies indicated that this R-M system is most probably of type IC.
对乳酸乳球菌质粒pIL2614中编码I型限制-修饰(R-M)系统的核酸内切酶、甲基化酶和特异性亚基的三个基因进行了表征。质粒定位、序列同源性和失活研究表明,该R-M系统很可能属于IC型。
