Regulation of Purine Biosynthesis. The PRPP amidotransferase enzyme exists as an active monomer and an inactive polymer (see Introduction to Metabolism Lecture). IMP, GMP and AMP all inactivate the enzyme causing a shift towards the polymerized inactive form. PRPP causes a shift towards the active monomeric form.
As ANP synthesis is enhanced by the latter, it suggests a regulatory loop. Moreover ANP inhibits the thyroid synthesis whereas its production is enhanced by thyroid hormone. The hypothalamo-hypophyseal axis is another important target. ANP inhibits ACTH release and arginine vasopressin secretion.1)Service d'endocrinologie et maladies metaboliques, MÃ©taboliques Clinique-Marc, LINQUETTE-Usn, A, chru, 6 rue Du-Professeur, laguesse 59037 Lille.
