19. Data suggest CYP17A1, with electron donor NADPH-P450 reductase, is inherently distributive enzyme but that some processivity is present; some 17alpha-hydroxy pregnenolone formed does not dissociate from CYP17A1 before conversion to dehydroepiandrosterone; CYP5A does not enhance reaction by decreasing k(off) of ligands of CYP17A1. (CYP17A1 = cytochrome P450, family 17, subfamily A, polypeptide 1; CYP5A = cytochrome b5) PMID: 28684414
20. we identified a novel (K144del) and a widely reported (Y329 fs) heterozygous mutations of CYP17A1 gene from a 17OHD patient. Haplotyping analysis showed the common mutation Y329 fs in China came from the same ancestor, which explains the reason that 17OHD was the second cause of congenital adrenal hyperplasia in China. PMID: 27150612
21. The activities of P450 17A1 are regulated by cyt b5 that enhances the 17,20-lyase reaction by promoting the coupling of P450 17A1 and cytochrome P450 reductase (CPR), allosterically. Cyt b5 can also act as an electron donor to enhance the 16-ene-synthase activity of human P450 17A1. PMID: 26976652
22. The results showed that CYP17A1 gene was not conclusively linked to either Insulin resistance (IR) or its associated increased androgen secretion in non-obese women with polycystic ovarian syndrome (PCOS). We propose that an increased sensitivity of insulin on the ovarian cells may be the predominant reason for the clinical effects and symptoms of androgen excess observed in non-obese PCOS patients in our region.

25. For the naturally occurring P450 17A1 mutations E305G and R347H, which impair 17,20-lyase activity, cytochrome b5 failed to rescue the poor coupling with 17-hydroxypregnenolone (2-4%). When the conserved active-site threonine was mutated to alanine (T306A), both the activity and coupling were markedly decreased with all substrates. PMID: 27426448
