EC 2.1.1.310

Accepted name: 25S rRNA (cytosine2870-C5)-methyltransferase

Reaction: S-adenosyl-L-methionine + cytosine2870 in 25S rRNA = S-adenosyl-L-homocysteine + 5-methylcytosine2870 in 25S rRNA

Other name(s): NOP2 (gene name)

Systematic name: S-adenosyl-L-methionine:25S rRNA (cytosine2870-C5)-methyltransferase

Comments: The enzyme, found in eukaryotes, is specific for cytosine2870 of the 25S ribosomal RNA. The numbering corresponds to the enzyme from the yeast Saccharomyces cerevisiae [1].
