Hypoxanthine-guanine phosphoribosyltransferase (HGPRT) is a key enzyme in purine salvage pathways. This enzyme salvages guanine directly and adenine indirectly from catabolism.

Introduction
Hypoxanthine-guanine phosphoribosyltransferase (HGPRT) is a key enzyme in purine salvage pathways. This enzyme salvages guanine directly and adenine indirectly from catabolism. It catalyzes the reversible transfer of the phosphoribosyl group from a-D-5-phosphoribosyl 1-pyrophosphate (PRPP) to hypoxanthine or guanine forming either IMP or GMP, respectively. This reaction is dependent on a divalent magnesium cation. HGPRT is deficient in Lesch-Nyhan syndrome, a sever neurological disorder characterized by high levels of blood uric acid and uncontrollable self mutilation. A partial deficiency of the enzyme leads to gouty arthritis. [1]
