Function
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.
Catalytic activity
- adenosine1518/adenosine1519 in 16S rRNA + 4 S-adenosyl-L-methionine = 4 H+ + N6-dimethyladenosine1518/N6-dimethyladenosine1519 in 16S rRNA + 4 S-adenosyl-L-homocysteine
