Protein attributes

Sequence length	429 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	This methylase recognizes the double-stranded sequence ACCGGT, causes specific methylation on C-? on both strands, and protects the DNA from cleavage by the AgeI endonuclease.
Catalytic activity	S-adenosyl-L-methionine + DNA = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine.
Sequence similarities	Belongs to the C5-methyltransferase family.
