CC   -!- FUNCTION: A methylase, recognizes the double-stranded sequence 5'-
CC       GCCGGC-3', methylates C-2 on both strands, and protects the DNA from
CC       cleavage by the NgoMIV endonuclease. {ECO:0000269|PubMed:1321116,
CC       ECO:0000303|PubMed:12654995}.
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}.
CC   -!- CAUTION: Was originally known as M.NgoMI. {ECO:0000305|PubMed:1321116}.
