Uridine phosphorylase from Salmonella typhimurium (StUP) catalyzes the reversible phosphorolysis of uridine with the formation of ribose-1-phosphate and uracil.
Upase, Recombinant (Salmonella typhimurium)
UrdPase; Upase; StUP
Sterile Filtered white lyophilized powder.
Uridine phosphorylase Salmonella typhimurium Recombinantproduced in E. coli is a non-glycosylated, polypeptide having a total molecular mass of 163068 Dalton.
Enzyme Commission Number
Greater than 95.0% as determined by SDS-PAGE.
One unit phosphorylates 1μm of uridine within 1 min at pH 7.3.
Lyophilized UPase although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution UPase should be stored at 4°C between 2-7 days and for future use below -18°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
The UPase was lyophilized from 1mg/ml solution containing 25mM Tris-HCl, pH 8.0, 0.15M NaCl.
