Protein

Ribosomal RNA small subunit methyltransferase A

Gene

rsmA

Organism
Helicobacter pylori (strain ATCC 700392 / 26695) (Campylobacter pylori)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

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.UniRule annotation
