CC -!- FUNCTION: A beta subtype methylase that recognizes the double-stranded
CC sequence 5'-GANTC-3' and methylates on A-2 on both strands
CC (PubMed:12654995) (By similarity). Overexpression from a moderate-copy
CC number plasmid (10-12 copies/cell) leads to enlarged, branched cells,
CC many with 3-5 genome equivalents. Contributes to the accurate cell-
CC cycle control of DNA replication and cellular morphology
CC (PubMed:10852881). {ECO:0000250|UniProtKB:O30569,
CC ECO:0000269|PubMed:10852881, 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 homocysteine; Xref=Rhea:RHEA:15197, Rhea:RHEA-COMP:12418, Rhea:RHEA-
CC COMP:12419, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:90615, ChEBI:CHEBI:90616; EC=2.1.1.72;
CC -!- INDUCTION: By CtrA. {ECO:0000269|PubMed:9294447}.
CC -!- DISRUPTION PHENOTYPE: Essential, it cannot be disrupted.
CC {ECO:0000269|PubMed:10852881}.
CC -!- SIMILARITY: Belongs to the N(4)/N(6)-methyltransferase family.
CC {ECO:0000305}.
