DNA Cytosine Methylases; DNA Modification Methylases Cytosine Specific; Modification Methylases (Cytosine Specific); Site Specific Methyltransferases (Cytosine Specific); Cytosine Methylases, DNA; Methylases, DNA Cytosine; Methylases, DNA-Cytosine
An enzyme responsible for producing a species-characteristic methylation pattern on cytosine residues in a specific short base sequence in the host cell's DNA. The enzyme catalyzes the methylation of DNA cytosine in the presence of S-adenosyl-L-methionine to form S-adenosyl-L-homocysteine and DNA containing 5-methylcytosine. EC 2.1.1.73.
