23S rRNK (adenin2085-N6)-dimetiltransferaza (EC 2.1.1.184, ErmC' metiltransferaza, ermC metilaza, ermC 23S rRNK metiltransferaza, rRNK:m6A metiltransferaza ErmC' , ErmC' , rRNK metiltransferaza ErmC' ) je enzim sa sistematskim imenom S-adenozil-L-metionin:23S rRNK (adenin2085-N6)-dimetiltransferaza.[1][2][3][4][5][6] Ovaj enzim katalizuje sledeću hemijsku reakciju
- 2 S-adenozil-L-metionin + adenin2085 u 23S rRNK 2 S-adenozil-L-homocistein + N6-dimetiladenin2085 u 23S rRNK
ErmC je metiltransferaza koja pruža otpornost na makrolid-linkozamid-streptograminsku B grupu antibiotika tako što katalizuje metilaciju 23S rRNK na adeninu2085.
