Comments

FUNCTION: This methylase recognizes the double-stranded sequence GRCGYC, causes specific methylation on C-? on both strands, and protects the DNA from cleavage by the HgiDI endonuclease.
CATALYTIC ACTIVITY: S-adenosyl-L-methionine + DNA = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine.
SIMILARITY: Belongs to the C5-methyltransferase family.
