16S rRNK (citidin1409-2'-O)-metiltransferaza (EC 2.1.1.227, TlyA (nespecifična)) je enzim sa sistematskim imenom S-adenozil-L-metionin:16S rRNK (citidin1409-2'-O)-metiltransferaza.[1][2] Ovaj enzim katalizuje sledeću hemijsku reakciju
- S-adenozil-L-metionin + citidin1409 u 16S rRNK S-adenozil-L-homocistein + 2'-O-metilcitidin1409 u 16S rRNK
Bifunkcionalni enzim iz Mycobakterija tuberculosis 2'-O-metiliše citidin1409 u heliksu 44 u 16S rRNK i citidin1920 u heliksu 69 u 23S rRNK (cf. EC 2.1.1.226, 23S rRNK (citidin1920-2'-O)-metiltransferaza).
