Options :

  2. Isocitrate dehydrogenase
  3. Xanthine oxidoreductase
  4. adenine phosphoribosyltransferase
Answer and Explanation :-

Answer: Option 1


HGPRT is a transferase that catalyzes conversion of hypoxanthine to inosine monophosphate and guanine to guanosine monophosphate. HGPRT plays a central role in the generation of purine nucleotides through the purine salvage pathway. Lesch-Nyhan syndrome is due to HPRT mutations resulting in extremely ineffective enzyme activity.
