Function
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
- D-ribose 5-phosphate + uracil = psi-UMP + H2O
Cofactor
Note: Binds 1 Mn2+ ion per subunit.
