23S rRNK (adenozin1067-2'-O)-metiltransferaza (EC 2.1.1.230, 23S rRNK A1067 2'-metiltransferaza, metilaza tiostreptonske otpornosti, metiltransferaza nosiheptidne otrpornosti) je enzim sa sistematskim imenom S-adenozil-L-metionin:23S rRNK (adenozin1067-2'-O)-metiltransferaza.[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju
- S-adenozil-L-metionin + adenozin1067 u 23S rRNK S-adenozil-L-homocistein + 2'-O-metiladenozin1067 u 23S rRNK
Ova metilaza je odgovorna za autoimunost Streptomyces azureus koji formira tiostrepton.
