Thus, the two substrates of this enzyme are ATP and pseudouridine, whereas its two products are ADP and pseudouridine 5'-phosphate.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:pseudouridine 5'-phosphotransferase. This enzyme is also called pseudouridine kinase (phosphorylating). This enzyme participates in pyrimidine metabolism.
