Abstract
The genes for over 100 restriction-modification systems have now been cloned, and approximately one-half have been sequenced. Despite their similar function, they are exceedingly heterogeneous. The heterogeneity is evident at three levels: in the gene arrangements; in the enzyme compositions; and in the protein sequences. This paper summarizes the main features of the R-M systems that have been cloned.Mesh:
