Protein attributes

Sequence length	420 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

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