Corticosterone synthesis pathway

WebTerminal steroidogenic pathway mediated by CYP11B1 (cortisol synthase) and CYP11B2 (aldosterone synthase) leading to cortisol (A) and aldosterone (B). At the amino acid level, AS (CYP11B2) is 93% identical to cortisol synthase (CS; CYP11B1) ( Mornet, Dupont, Vitek, & White, 1989 ). WebJun 25, 2024 · Interestingly, although the lung expresses all the steroidogenic enzymes required for de novo synthesis, analysis of lung GC synthesis revealed that the predominant pathway by which corticosterone is produced is by reactivation from inactive serum-derived dehydrocorticosterone via 11β-HSD1 enzyme ( 79 ).

WebRat adrenal steroidogenesis has been measured in a system consisting of mitochondria, microsomes, succinate, Mg++, TPNH, DPN+, and phosphate. With incubations at 20°, the rate of corticosterone formation has been found to be biphasic with a rapid primary rate lasting for about 4 to 6 min, followed by a slower secondary rate which continues for at … WebThe first enzyme in the pathway is cytochrome P450scc, also known as cholesterol side chain cleavage enzyme. P450scc catalyzes the first, slowest, and therefore, rate limiting step for hormone synthesis. As you might expect from the observation that P450scc catalyzes the rate-limiting step, P450scc is also the major site of physiological ...
