CC -!- FUNCTION: Specifically dimethylates two adjacent adenosines (A1518 and
CC A1519) in the loop of a conserved hairpin near the 3'-end of 16S rRNA
CC in the 30S particle. May play a critical role in biogenesis of 30S
CC subunits. {ECO:0000255|HAMAP-Rule:MF_00607}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosine(1518)/adenosine(1519) in 16S rRNA + 4 S-adenosyl-L-
CC methionine = 4 H(+) + N(6)-dimethyladenosine(1518)/N(6)-
CC dimethyladenosine(1519) in 16S rRNA + 4 S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:19609, Rhea:RHEA-COMP:10232, Rhea:RHEA-COMP:10233,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:74411, ChEBI:CHEBI:74493; EC=2.1.1.182;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00607};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00607}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. rRNA adenine N(6)-methyltransferase family. RsmA
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00607}.
