2.4.2.22 | 5-phospho-alpha-D-ribose 1-diphosphate + xanthine |
the enzyme is involved in purine nucleotide synthesis via phosphorylation of purines acquisited from the host, since Leishmania donovani is not able to perform de novo biosynthesis of purine nucleotides |

reaction of EC 2.4.2.8 |
2.4.2.22 | more |
either hypoxanthine-guanine phosphoribosyltransferase or xanthine phosphoribosyltransferase is absolutely essential for purine acquisition, parasite viability, and parasite infectivity of mouse macrophages |
2.4.2.22 | more |
xanthine phosphoribosyltransferase is involved in acquirement of purine nutrients of Leimania from the host, the enzyme is not essential for purine salvage or viability |
