In enzymology, an UTP—xylose-1-phosphate uridylyltransferase ( EC 2.7.7.11) is an enzyme that catalyzes the chemical reaction
- UTP + alpha-D-xylose 1-phosphate diphosphate + UDP-xylose
Thus, the two substrates of this enzyme are UTP and alpha-D-xylose 1-phosphate, whereas its two products are diphosphate and UDP-xylose.
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:alpha-D-xylose-1-phosphate uridylyltransferase. Other names in common use include xylose-1-phosphate uridylyltransferase, uridylyltransferase, xylose 1-phosphate, UDP-xylose pyrophosphorylase, uridine diphosphoxylose pyrophosphorylase, and xylose 1-phosphate uridylyltransferase. This enzyme participates in nucleotide sugars metabolism.
