ID 2.1.1.310 DE 25S rRNA (cytosine(2870)-C(5))-methyltransferase. CA cytidine(2870) in 25S rRNA + S-adenosyl-L-methionine = CA 5-methylcytidine(2870) in 25S rRNA + H(+) + S-adenosyl-L-homocysteine. CC -!- The enzyme, found in eukaryotes, is specific for cytosine(2870) of CC the 25S ribosomal RNA. CC -!- The numbering corresponds to the enzyme from the yeast Saccharomyces CC cerevisiae.
