| 2.4.2.1 | medicine | the purine nucleoside phosphorylases may play a role in chemotherapy in two ways: 1. by catalyzing the breakdown of nucleosides that contain purine analogs and by promoting the incorporation of purine and pyrimidine analogs into the nucleotides and nucleic acids of the cell by increasing the intracellular pool of ribose 1-phosphate and deoxyribose 1-phosphate | Homo sapiens |
