Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Contents 1 Function 2 Relevance 3 Structural highlights 4 = 3D Structures of uridine phosphorylase Function Uridine phosphorylase (UPP) catalyzes the conversion of uridine or deoxyuridine and phosphate to uracil and α-D-ribose 1-phosphate. UPP is part of RNA or DNA biosynthesis[1]. Unhydrouridine is an inhibitor of UPP. Relevance UPP inhibitors are tested for prevention of mucositis during chemotherapy[2].
