CC   -!- FUNCTION: Specifically dimethylates two adjacent adenosines in the loop
CC       of a conserved hairpin near the 3'-end of 18S rRNA in the 40S particle.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=adenosine(1779)/adenosine(1780) in 18S rRNA + 4 S-adenosyl-L-
CC         methionine = 4 H(+) + N(6)-dimethyladenosine(1779)/N(6)-
CC         dimethyladenosine(1780) in 18S rRNA + 4 S-adenosyl-L-homocysteine;
CC         Xref=Rhea:RHEA:42780, Rhea:RHEA-COMP:10234, Rhea:RHEA-COMP:10236,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC         ChEBI:CHEBI:74411, ChEBI:CHEBI:74493; EC=2.1.1.183;
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}.
