mRNA (cytidine-5-)-methyltransferase activity
mrna (cytidine-5-)-methyltransferase activity
a cytidine in mRNA + S-adenosyl-L-methionine = a 5-methylcytidine in mRNA + S-adenosyl-L-homocysteine + H(+)
a cytidine in mrna + s-adenosyl-l-methionine = a 5-methylcytidine in mrna + s-adenosyl-l-homocysteine + h(+)
