Protein
Ribosomal RNA small subunit methyltransferase A
Organism
Mycobacterium tuberculosis (strain CDC 1551 / Oshkosh)
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.
Similarity
Belongs to the class I-like SAM-binding methyltransferase superfamily. rRNA adenine N(6)-methyltransferase family. RsmA subfamily.
