23S rRNA (cytosine1962-C5)-methyltransferase (EC 2.1.1.191, RlmI, rRNA large subunit methyltransferase I, YccW) is an enzyme with systematic name S-adenosyl-L-methionine:23S rRNA (cytosine1962-C5)-methyltransferase.[1][2] This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + cytosine1962 in 23S rRNA S-adenosyl-L-homocysteine + 5-methylcytosine1962 in 23S rRNA

The enzyme specifically methylates cytosine1962 at C5 in 23S rRNA.
