| Description: | Cytochrome P450, 17-20 lyase (CYP17-lyase) assay development using recombinant human CYP17 enzyme and 17-alpha -hydroxy pregnenolone [21-3H] as the substrate.Cytochrome P450,17-alpha -Hydroxylase, 17-20 lyase (CYP17) is a multi functional enzyme that plays a key role in the biosynthesis of steroid hormones. It catalyses both conventional hydroxylation and also the carbon-carbon bond cleavage reactions (Peter Lee-Robichaud et al, Biochem. J, (1997) 321, 857-63). In the hydroxylation reaction, it converts progesterone and pregnenolone to the corresponding hydroxylated products 17-alpha -hydroxy progesterone and 17-alpha -hydroxy pregnenolone. In the lyase reaction, it catalyzes the conversion of these hydroxylated substrates to Androstenedione and Dehydroepiandrosterone (DHEA) respectively. In the Cyp17 lyase assay described here, the conversion of 17-alpha -hydroxy pregnenolone to Dehydroepiandrosterone and acetic acid is being monitored. |
