Function
function
A beta subtype methylase, recognizes the double-stranded sequence 5'-CCCGGG-3', methylates C-2 on both strands, and protects the DNA from cleavage by the XcyI endonuclease.
Catalytic activity
- a 2'-deoxycytidine in DNA + S-adenosyl-L-methionine = an N4-methyl-2'-deoxycytidine in DNA + S-adenosyl-L-homocysteine + H+
