| Accepted name: |
16S rRNA (cytidine1402-2′-O)-methyltransferase |
| Reaction: |
S-adenosyl-L-methionine + cytidine1402 in 16S rRNA = S-adenosyl-L-homocysteine + 2′-O-methylcytidine1402 in 16S rRNA |
| Other name(s): |
RsmI; YraL |
| Systematic name: |
S-adenosyl-L-methionine:16S rRNA (cytidine1402-2′-O)-methyltransferase |
| Comments: |
RsmI catalyses the 2′-O-methylation of cytidine1402 and RsmH (EC 2.1.1.199) catalyses the N4-methylation of cytidine1402 in 16S rRNA. Both methylations are necessary for efficient translation initiation at the UUG and GUG codons. |
