Template:Short description Template:Infobox enzyme In enzymology, a RNA uridylyltransferase (EC 2.7.7.52) is an enzyme that catalyzes the chemical reaction

UTP + RNAn diphosphate + RNAn+1

Thus, the two substrates of this enzyme are UTP and RNAn, whereas its two products are diphosphate and RNAn+1.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is UTP:RNA uridylyltransferase. Other names in common use include terminal uridylyltransferase, and TUT.

Structural studies

As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes 2E5G, 2IKF, 2NOM, 2Q0C, 2Q0D, 2Q0E, 2Q0F, and 2Q0G.
