CC   -!- FUNCTION: A methylase that recognizes the double-stranded sequence 5'-
CC       GGNCC-3', methylates C-? on both strands, and protects the DNA from
CC       cleavage by both the Eco47I and Eco47II endonucleases.
CC       {ECO:0000303|PubMed:12654995, ECO:0000305|PubMed:7607524}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 2'-deoxycytidine in DNA + S-adenosyl-L-methionine = a 5-
CC         methyl-2'-deoxycytidine in DNA + H(+) + S-adenosyl-L-homocysteine;

CC         Evidence={ECO:0000255|PROSITE-ProRule:PRU10018};
CC   -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC       superfamily. C5-methyltransferase family. {ECO:0000255|PROSITE-
CC       ProRule:PRU01016}.
