Comments [?]

Function Catalyzes the reversible cleavage of pseudouridine 5'-phosphate (PsiMP) to ribose 5-phosphate and uracil. Functions biologically in the cleavage direction, as part of a pseudouridine degradation pathway.
Catalytic activity RHEA:18337: D-ribose 5-phosphate + uracil = H2O + psi-UMP
EC 4.2.1.70
Cofactor Mn(2+)
Note: Binds 1 Mn(2+) ion per subunit.
Subunit Homotrimer.
Similarity Belongs to the pseudouridine-5'-phosphate glycosidase family.
