RsmA from Methanocaldococcus jannaschii - protein summary.
Ribosomal RNA small subunit methyltransferase A
KsgA, Dim1, MJ1029
Position of modification - modification:
Archaeal RsmA belongs to the bacterial KsgA/eukaryal Dim1 super family of methyltransferases. It dimethylates two very conserved adjacent adenosines (positions 1518 and 1519 in E.coli numbering) in the loop of a conserved hairpin near the 3'-end of small subunit rRNA. AdoMet is the methyl group donor. Identity of the target nucleotides was identified by using a heterologous rRNA substrate.
Recognition of a complex substrate by the KsgA/Dim1 family of enzymes has been conserved throughout evolution.
