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 {ECO:0000256|ARBA:ARBA00002977}.
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 Evidence={ECO:0000256|ARBA:ARBA00000248};
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. rRNA adenine N(6)-methyltransferase family.
CC {ECO:0000256|PROSITE-ProRule:PRU01026, ECO:0000256|RuleBase:RU362106}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:RFU79761.1}.
