23S rRNA (cytosine1962-C5)-methyltransferase (EC 2.1.1.191 RlmI rRNA large subunit methyltransferase I YccW) is an enzyme with system name S-adenosyl-L-methionine:23S rRNA (cytosine1962-C5)-methyltransferase. This enzyme catalyses the following chemical reaction S-adenosyl-L-methionine + cytosine1962 in 23S rRNA S-adenosyl-L-homocysteine + 5-methylcytosine1962 in 23S rRNAThe enzyme specifically methylates cytosine1962 at C5 in 23S rRNA.
