Enzyme Information
| 2.1.1.198 |
16S rRNA (cytidine(1402)-2'-O)-methyltransferase.
based on mapping to UniProt P67087
S-adenosyl-L-methionine + cytidine(1402) in 16S rRNA = S-adenosyl-L- homocysteine + 2'-O-methylcytidine(1402) in 16S rRNA.
-!- RsmI catalyzes the 2'-O-methylation of cytidine(1402) and RsmH (EC 2.1.1.199) catalyzes the N(4)-methylation of cytidine(1402) in 16S rRNA. -!- Both methylations are necessary for efficient translation initiation at the UUG and GUG codons.
