CC   -!- FUNCTION: A beta subtype methylase that recognizes the double-stranded
CC       sequence 5'-GANTC-3' and methylates A-2 on both strands
CC       (PubMed:12654995) (By similarity). CcrM-mediated methylation has
CC       important cellular functions. Contributes to the accurate cell-cycle
CC       control of DNA replication and cellular morphology (By similarity).
CC       {ECO:0000250|UniProtKB:O30569, ECO:0000250|UniProtKB:Q2YMK2,
CC       ECO:0000303|PubMed:12654995}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 2'-deoxyadenosine in DNA + S-adenosyl-L-methionine = an
CC         N(6)-methyl-2'-deoxyadenosine in DNA + H(+) + S-adenosyl-L-

CC         ChEBI:CHEBI:90615, ChEBI:CHEBI:90616; EC=2.1.1.72;
CC   -!- SIMILARITY: Belongs to the N(4)/N(6)-methyltransferase family.
