A nucleoside phosphorylase:

1. cleaves a nucleoside with the production of ribose 1-phosphate.

2. is necessary for the major salvage pathway for pyrimidines.

3. is used in the degradation of purine nucleotides.

4. is responsible for the equilibration of nucleoside monophosphates and nucleoside diphosphate.
