Specific function: Specifically dimethylates two adjacent adenosines (A1518 and A1519) in the loop of a conserved hairpin near the 3'-end of 16S rRNA in the 30S particle. May play a critical role in biogenesis of 30S subunits

COG id: COG0030

COG function: function code J; Dimethyladenosine transferase (rRNA methylation)

Gene ontology:

Cell location: Cytoplasm (Potential)

Metaboloic importance: Non_Essential [C]

Operon status: Not Known

Operon components: None

Similarity: Belongs to the methyltransferase superfamily. rRNA adenine N(6)-methyltransferase family. RsmA subfamily
