HGPRT

(= hypoxanthine-guanine phosphoribosyl transferase) Enzyme that catalyses the first step in the pathway for salvage of the purines hypoxanthine and guanine. The phosphoribosyl moiety is transferred from an activated precursor, 5-phosphoribosyl 1-pyrophosphate. Since animal cells can synthesize purines de novo , HGPRT-mutants can be selected by their resistance to toxic purine analogues. A genetic lesion in HGPRT in humans underlies the Lesch-Nyhan syndrome. See HAT medium. ...
