Schematic overview of fluoropyrimidine metabolism in T. b. brucei and Leishmania species. Red boxes and arrows represent metabolites and reactions, respectively, observed in both T. brucei and Leishmania species; Blue boxes and arrows are observed only in T. brucei and green arrows represent reactions observed only in the Leishmania species; black boxes and arrows indicate reactions that do not happen in either species. The curved blue bar schematically represents the plasma membrane of the parasites. Enzyme reactions are indicated with numbers as follows. 1, Uridine Phosphorylase and/or Thymidine Phosphorylase; 2, Uracil Phosphoribosyl transferase; 3, Nucleoside Diphosphatase; 4, Nucleoside Diphosphate Kinase; 5, Cytidine Triphosphate Synthase; 6, Ribonucleoside-diphosphate Reductase; 7, Thymidylate Kinase; 8, Thymidine Kinase; 9, UTP:N-acetyl-a-D-glucosamine-1-phosphate Uridylyltransferase; 10, UDP-Glucose Pyrophosphorylase; 11, UDP-Glucose Epimerase; 12, Phosphatidate Cytidylyltransferase; 13, Ethanolamine-phosphate Cytidylyltransferase; 14, Choline-phosphate Cytidylyltransferase; 15, RNA Polymerase.
