CC   -!- FUNCTION: A putative methylase that probably protects DNA from cleavage
CC       by the MjaORF1200P endonuclease. {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   -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC       superfamily. C5-methyltransferase family. {ECO:0000255|PROSITE-
CC       ProRule:PRU01016}.
