Research Progress on Uridine Phosphorylase in Vertebrate and Parasites

Abstract

Abstract:

Uridine phosphorylase（UPP） is a key enzyme of pyrimidine salvage pathways， catalyzing the reversible phosphorolysis of ribosides of uracil to nucleobases and ribose 1-phosphate. UPP plays an important role in the regulation of uridine homeostasis. Although UPP from a variety of organisms have many similarities in their functions， there are differences in many other aspects， such as physical and chemical properties， structure characteristics， active sites， and substrate binding sites. Therefore， UPP has broad application prospects in the design and development of antibacterial， antiparasitic drugs. This article summarizes the physico-chemical property and research progress of UPP from a variety of organisms， in order to integrate information of UPP， provide theoretic basis for further study of Toxoplasma gondii UPP protein as a feasible target antigen for toxoplasmosis vaccination.

Key words: Uridine phosphorylase, Pyrimidine salvage pathway, Toxoplasma gondii, Vaccine, Target
