Abstract

The presence of CC(A/T)GG sequences with methylated internal cytosine (Dcm methylation) was determined in DNA from different genera of eubacteria. This methylation was studied by using restriction enzymes EcoRII and BstNI, which cleave unmethylated or methylated CC(A/T)GG sequences. Dcm methylation was only detected in genera of the family Enterobacteriaceae closely related to Escherichia: Shigella, Citrobacter, Salmonella, and Klebsiella.
