CC   -!- FUNCTION: This protein produces a dimethylation of the adenine residue
CC       at position 2085 in 23S rRNA, resulting in reduced affinity between
CC       ribosomes and macrolide-lincosamide-streptogramin B antibiotics.
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=adenosine(2085) in 23S rRNA + 2 S-adenosyl-L-methionine = 2
CC         H(+) + N(6)-dimethyladenosine(2085) in 23S rRNA + 2 S-adenosyl-L-
CC         homocysteine; Xref=Rhea:RHEA:42784, Rhea:RHEA-COMP:10237, Rhea:RHEA-
CC         COMP:10238, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC         ChEBI:CHEBI:74411, ChEBI:CHEBI:74493; EC=2.1.1.184;
CC   -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC       superfamily. rRNA adenine N(6)-methyltransferase family.
CC       {ECO:0000255|PROSITE-ProRule:PRU01026}.
