Protein attributes

Sequence length	413 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 GCCGGC, causes specific methylation on C-? on both strands, and protects the DNA from cleavage by the NaeI endonuclease.
Catalytic activity	S-adenosyl-L-methionine + DNA = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine.
Sequence similarities	Belongs to the C5-methyltransferase family.
