- Protein existenceInferred from homology
- Annotation score2/5
Function
function
Catalyzes the reversible phosphorylytic cleavage of uridine to uracil and ribose-1-phosphate which can then be utilized as carbon and energy sources or in the rescue of pyrimidine bases for nucleotide synthesis. Shows broad substrate specificity and can also accept deoxyuridine and other analogous compounds.
Catalytic activity
- phosphate + uridine = alpha-D-ribose 1-phosphate + uracil
Pathway
Pyrimidine metabolism; UMP biosynthesis via salvage pathway; uracil from uridine (phosphorylase route): step 1/1.
Features
Showing features for binding site.
