Fibrillarin-like rRNA/tRNA 2'-O-methyltransferase

Gene

flpA

Organism
Archaeoglobus fulgidus (strain ATCC 49558 / VC-16 / DSM 4304 / JCM 9628 / NBRC 100126)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Involved in pre-rRNA and tRNA processing. Utilizes the methyl donor S-adenosyl-L-methionine to catalyze the site-specific 2'-hydroxyl methylation of ribose moieties in rRNA and tRNA. Site specificity is provided by a guide RNA that base pairs with the substrate. Methylation occurs at a characteristic distance from the sequence involved in base pairing with the guide RNA.UniRule annotation1 Publication
