FunFam 3: Ribosomal RNA small subunit methyltransferase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
RRNA small subunit pseudouridine methyltransferase Nep1. [EC: 2.1.1.260]
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.
