>TIGR00235 udk uridine kinase; InterPro: IPR000764 Uridine kinase (pyrimidine ribonucleoside kinase) is the rate-limiting enzyme in the pyrimidine salvage pathway. It catalyzes the following reaction: ATP + Uridine = ADP + UMP A cDNA for uridine kinase from mouse brain was found which encodes a protein of 277 amino acids. A truncated form of the cDNA was expressed in Escherichia coli, and shown to display uridine kinase activity and to readily form a tetramer, the most active form of the wild-type enzyme. Sequence analysis has identified three ATP-binding site consensus motifs. The predicted secondary structure, and sequence comparison with kinases of known structure, is consistent with uridine kinase having the alpha/beta core nucleotide-binding fold common to many kinases .; GO: 0005524 ATP binding, 0016773 phosphotransferase activity alcohol group as acceptor.
