Pseudouridine-5'-phosphate glycosidase

UniProtKB accession:  Q84K35

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the reversible cleavage of pseudouridine 5'-phosphate (PsiMP) to ribose 5-phosphate and uracil (PubMed:31907295). Functions biologically in the cleavage direction, as part of a pseudouridine degradation pathway (PubMed:31907295). Acts together with the pseudouridine kinase PUKI in the peroxisome to prevent toxic pseudouridine monophosphate accumulation (PubMed:31907295). Can catalyze the formation of pseudouridine 5'-phosphate (reverse reaction) in vitro, with a catalytic efficiency 4 times lower than the hydrolysis reaction (PubMed:31907295).
