General annotation (Comments)

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 By similarity. HAMAP-Rule MF_00607 SAAS SAAS020596

Catalytic activity

4 S-adenosyl-L-methionine + adenine(1518)/adenine(1519) in 16S rRNA = 4 S-adenosyl-L-homocysteine + N(6)-dimethyladenine(1518)/N(6)-dimethyladenine(1519) in 16S rRNA. HAMAP-Rule MF_00607 SAAS SAAS020596

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00607 SAAS SAAS023165.

Sequence similarities

Belongs to the class I-like SAM-binding methyltransferase superfamily. rRNA adenine N(6)-methyltransferase family. RsmA subfamily. HAMAP-Rule MF_00607
