Protein attributes

Sequence length	386 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	This methylase recognizes the double-stranded sequence GANTC and causes specific methylation on A-2 on both strands. CcrM-mediated methylation has important cellular functions. Appears to contribute to the accurate cell-cycle control of DNA replication and cellular morphology. Essential for viability By similarity.
Catalytic activity	S-adenosyl-L-methionine + DNA adenine = S-adenosyl-L-homocysteine + DNA 6-methylaminopurine.
Sequence similarities	Belongs to the N(4)/N(6)-methyltransferase family.
