ENZYME entry: EC 2.1.1.260

Accepted Name
rRNA small subunit pseudouridine methyltransferase Nep1.
Reaction catalysed
S-adenosyl-L-methionine + pseudouridine(1191) in yeast 18S rRNA <=> S-adenosyl-L-homocysteine + N(1)-methylpseudouridine(1191) in yeast 18S rRNA
Comment(s)
  • This enzyme, which occurs in both prokaryotes and eukaryotes, recognizes specific pseudouridine residues (Psi) in small subunits of ribosomal RNA based on the local RNA structure.
  • It recognizes Psi(914) in 16S rRNA from the archaeon Methanocaldococcus jannaschii, Psi(1191) in yeast 18S rRNA, and Psi(1248) in human 18S rRNA.
