2.1.1.199 |
Accepted name: |
16S rRNA (cytosine1402-N4)-methyltransferase |
Reaction: |
S-adenosyl-L-methionine + cytosine1402 in 16S rRNA = S-adenosyl-L-homocysteine + N4-methylcytosine1402 in 16S rRNA |
Other name(s): |
RsmH; MraW |
Systematic name: |
S-adenosyl-L-methionine:16S rRNA (cytosine1402-N4)-methyltransferase |
Comments: |
RsmH catalyses the N4-methylation of cytosine1402 and RsmI (EC 2.1.1.198) catalyses the 2′-O-methylation of cytosine1402 in 16S rRNA. Both methylations are necessary for efficient translation initiation at the UUG and GUG codons. |
