CC -!- FUNCTION: An alpha subtype methylase, recognizes the double-stranded
CC sequence 5'-GATC-3' and methylates A-2 (Probable) (PubMed:12654995).
CC May be involved in methyl-directed DNA mismatch repair, initiation of
CC chromosome replication and gene expression (By similarity).

CC ECO:0000305|PubMed:8125341}.
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 homocysteine; Xref=Rhea:RHEA:15197, Rhea:RHEA-COMP:12418, Rhea:RHEA-
