FunFam 4594: Phosphorylase superfamily protein

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Purine-nucleoside phosphorylase. [EC: 2.4.2.1]
(1) Purine nucleoside + phosphate = purine + alpha-D-ribose 1-phosphate. (2) Purine deoxynucleoside + phosphate = purine + 2'-deoxy-alpha-D-ribose 1-phosphate.
  • Specificity not completely determined.
  • Can also catalyze ribosyltransferase reactions of the type catalyzed by EC 2.4.2.5.

Uridine phosphorylase. [EC: 2.4.2.3]
Uridine + phosphate = uracil + alpha-D-ribose 1-phosphate.
  • The enzyme participates the the pathways of pyrimidine ribonucleosides degradation and salvage.
  • The mammalian enzyme also accepts 2'-deoxyuridine.
  • Formerly EC 2.4.2.23.
