La adenina fosforribosiltransferasa, también conocida como APRT, es una enzima codificada La APRT posee el EC La APRT se encuentra funcionalmente relacionada con la hipoxantina-guanina fosforribosiltransferasa ( HPRT). (HGPRT) è un enzima codificato negli esseri umani dal gene HPRT1. L’HGPRT è una transferasi che catalizza la conversione dell’ipoxantina in inosina. pela deficiência na enzima hipoxantina- guanina fosforibosiltransferase. neurológicas em la deficiência de hipoxantina-guanina fosforribosiltransferasa.

Depending on the conditions it can give different compounds such as Alioxan, Uroxanic acid, Uric acid glycol ,Allantoin causingin all reactions peroxide which will be offset by the second enzyme system, catalase.

This system decompose uric acida waste product of purine degradation into allantoin and peroxide involving an enzyme called uricase.
