Comments
  • FUNCTION: This protein produces a dimethylation of the adenine residue at position 2058 in 23S rRNA, resulting in reduced affinity between ribosomes and macrolide-lincosamide-streptogramin B antibiotics.
  • CATALYTIC ACTIVITY: S-adenosyl-L-methionine + rRNA = S-adenosyl-L-homocysteine + rRNA containing N6-methyladenine.
  • SIMILARITY: Belongs to the rRNA adenine N(6)-methyltransferase family.
