Functional analysis of pyrimidine biosynthesis enzymes using the anticancer drug 5-fluorouracil in Caenorhabditis elegans.

21 Jul 2009 Pyrimidine biosynthesis enzymes function in many cellular processes and are closely associated with pyrimidine antagonists used in cancer chemotherapy. These enzymes are well characterized from bacteria to mammals, but not in a simple metazoan. To ... Read more...

Phosphorylation of dGMP analogs by vaccinia virus TMP kinase and human GMP kinase.

21 Jul 2009 Vaccinia virus thymidylate kinase, although similar in sequence to human TMP kinase, has broader substrate specificity and phosphorylates (E)-5-(2-bromovinyl)-dUMP and dGMP. Modified guanines such as glyoxal-dG, 8-oxo-dG, O(6)-methyl-dG, ... Read more...

The yeast Cdc8 exhibits both deoxythymidine monophosphate and diphosphate kinase activities.

16 Jun 2009 The existence of multifunctional enzymes in the nucleotide biosynthesis pathways is believed to be one of the important mechanisms to facilitate the synthesis and the efficient supply of deoxyribonucleotides for DNA replication. Here, we used the ... Read more...

Technical information about 'Nucleoside-Phosphate Kinase'

Definition: An enzyme that catalyzes reversible reactions of a nucleoside triphosphate, e.g., ATP, with a nucleoside monophosphate, e.g., UMP, to form ADP and UDP. Many nucleoside monophosphates can act as acceptor while many ribo- and deoxyribonucleoside triphosphates can act as donor. EC 2.7.4.4.

Chemical name: ATP:nucleoside-phosphate phosphotransferase

Registry Number: EC 2.7.4.4

Descriptor UI: D009703

Alternative terms: Nucleoside-Phosphate Kinase; Kinase, Nucleoside-Phosphate; Nucleoside Phosphate Kinase; Nucleoside Monophosphate Kinases; Kinases, Nucleoside Monophosphate; Monophosphate Kinases, Nucleoside;
