| pubmed-article:16660311 | pubmed:abstractText | A uracil phosphoribosyltransferase (UMP-pyrophosphorylase) was found in several angiosperms and was partially purified from epicotyls of pea (Pisum sativum L. cv. Alaska) seedlings. Its pH optimum was about 8.5; its required approximately 0.3 mm MgCl(2) for maximum activity but was inhibited by MnCl(2); its molecular weight determined by chromatography on Sephadex G-150 columns was approximately 100,000; its K(m) values for uracil and 5-phosphorylribose 1-pyrophosphate were 0.7 mum and 11 mum; and it was partially resolved from a similar phosphoribosyltransferase converting orotic acid to orotodine 5'-phosphate. Enzyme fractions containing both uracil phosphoribosyl transferase and orotate phosphoribosyltransferase converted 6-azauracil and 5-fluorouracil to products with chromatographic properties of 6-azauradine 5'-phosphate and 5-fluorouridine 5'-phosphate. Uracil phosphoribosyltransferase probably functions in salvage of uracil for synthesis of pyrimidine nucleotides. | lld:pubmed |
