CC   -!- FUNCTION: Catalyzes the reversible cleavage of pseudouridine 5'-
CC       phosphate (PsiMP) to ribose 5-phosphate and uracil. Functions
CC       biologically in the cleavage direction, as part of a pseudouridine
CC       degradation pathway. {ECO:0000255|HAMAP-Rule:MF_01876}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-ribose 5-phosphate + uracil = H2O + psi-UMP;
CC         Xref=Rhea:RHEA:18337, ChEBI:CHEBI:15377, ChEBI:CHEBI:17568,
CC         ChEBI:CHEBI:58380, ChEBI:CHEBI:78346; EC=4.2.1.70;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01876};
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01876};
CC       Note=Binds 1 Mn(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01876};
CC   -!- SUBUNIT: Homotrimer. {ECO:0000255|HAMAP-Rule:MF_01876}.
CC   -!- SIMILARITY: Belongs to the pseudouridine-5'-phosphate glycosidase
CC       family. {ECO:0000255|HAMAP-Rule:MF_01876}.
