Add article description

Site-specific DNA-methyltransferase (cytosine-N4-specific) (EC 2.1.1.113, modification methylase, restriction-modification system, DNA[cytosine-N4]methyltransferase, m4C-forming MTase, S-adenosyl-L-methionine:DNA-cytosine 4-N-methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:DNA-cytosine N4-methyltransferase.[1][2][3][4] This enzyme catalyses the following chemical reaction:

S-adenosyl-L-methionine + DNA cytosine S-adenosyl-L-homocysteine + DNA N4-methylcytosine
Quick Facts Identifiers, EC no. ...

This is a large group of enzymes.[5]
