rRNA small subunit pseudouridine methyltransferase Nep1.
based on mapping to UniProt Q06287
S-adenosyl-L-methionine + pseudouridine(1191) in yeast 18S rRNA = S-adenosyl-L-homocysteine + N(1)-methylpseudouridine(1191) in yeast 18S rRNA.
-!- 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.
