XMP ADP ATP XMP-glutamine amidotransferase GMP يا Increased levels of ADP inhibit the production of PRPP. Increased levels of GMP inhibit the production of XMP. Increased ADP activates PRPP synthase to increase PRPP levels. Increased IMP activates glutamine-PRPP amidotransferase to further increase IMP levels.
