Guanine 80-87 xanthine phosphoribosyltransferase Leishmania donovani 24-28 10567419-11 1999 Kinetic analysis revealed that the XPRT preferentially phosphoribosylated xanthine but could also recognize hypoxanthine and guanine. Guanine 125-132 xanthine phosphoribosyltransferase Leishmania donovani 35-39
