Protein attributes

Sequence length	244 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	This protein produces a dimethylation of the adenine residue at position 2085 in 23S rRNA, resulting in reduced affinity between ribosomes and macrolide-lincosamide-streptogramin B antibiotics.
Catalytic activity	2 S-adenosyl-L-methionine + adenine(2085) in 23S rRNA = 2 S-adenosyl-L-homocysteine + N(6)-dimethyladenine(2085) in 23S rRNA.
Sequence similarities	Belongs to the methyltransferase superfamily. rRNA adenine N(6)-methyltransferase family.
