Adenine phosphoribosyltransferase, also known as APRT, is a human gene.1

The protein encoded by this gene, APRTase is an enzyme involved in the purine nucleotide salvage pathway. It functions as a catalyst in the reaction between adenine and phosphoribosyl pyrophosphate (PRPP) to form AMP. APRTase is labeled as EC 2.4.2.7.

APRT is functionally related to hypoxanthine-guanine phosphoribosyltransferase (HPRT).

Pathology

Deficiency of APRT in human beings may lead to kidney stones formed of adenine and salts.

2,8 dihydroxy-adenine urolithiasis is also known as "adenine phosphoribosyltransferase deficiency".
