In enzymology, a [protein-PII] uridylyltransferase (EC 2.7.7.59) is an enzyme that catalyzes the chemical reaction
- UTP + [protein-PII] diphosphate + uridylyl-[protein-PII]
Thus, the two substrates of this enzyme are UTP and protein-PII, whereas its two products are diphosphate and [[uridylyl-[protein-PII]]].
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:[protein-PII] uridylyltransferase. Other names in common use include PII uridylyl-transferase, and uridyl removing enzyme. This enzyme participates in two-component system - general.
