Metabolite Identification
Common NameRibose 1-phosphate
DescriptionRibose 1-phosphate is an intermediate in the metabolism of Pyrimidine and the metabolism of Nicotinate and nicotinamide. It is a substrate for Uridine phosphorylase 2, Phosphoglucomutase, Purine nucleoside phosphorylase and Uridine phosphorylase 1. Ribose 1-phosphate can be formed from guanosine through the action of purine nucleoside phosphorylase. Ribose 1-phosphate can also act as a ribose donor in the synthesis of xanthosine as catalyzed by the same enzyme (purine nucleoside phosphorylase). The presence of guanase, which irreversibly converts guanine to xanthine, affects the overall process of guanosine transformation. As a result of this purine pathway, guanosine is converted into xanthosine, thus overcoming the lack of guanosine deaminase in mammals. The activated ribose moiety in Ribose 1-phosphate which stems from the catabolism of purine nucleosides can be transferred to uracil and, in the presence of ATP, used for the synthesis of pyrimidine nucleotides; therefore, purine nucleosides can act as ribose donors for the salvage of pyrimidine bases.
