2.1.1.227 |
| Accepted name: |
16S rRNA (cytidine1409-2′-O)-methyltransferase |
| Reaction: |
S-adenosyl-L-methionine + cytidine1409 in 16S rRNA = S-adenosyl-L-homocysteine + 2′-O-methylcytidine1409 in 16S rRNA
|
| Other name(s): |
TlyA (ambiguous) |
| Systematic name: |
S-adenosyl-L-methionine:16S rRNA (cytidine1409-2′-O)-methyltransferase |
| Comments: |
The bifunctional enzyme from Mycobacterium tuberculosis 2′-O-methylates cytidine1409 in helix 44 of 16S rRNA and cytidine1920 in helix 69 of 23S rRNA (cf. EC 2.1.1.226, 23S rRNA (cytidine1920-2′-O)-methyltransferase). |
