Abstract:
Within the superfamily of cytochrome P450 enzymes (P450s), there is a small class which is functionally
employed for steroid biosynthesis. The enzymes in this class appear to have a small active site to
accommodate the steroid substrates specifically and snuggly, prior to the redox transformation or hydroxylation
to form a product. Cytochrome P450c17 is one of these and is also a multi-functional P450,
with two activities, the first 17a-hydroxylation of pregnenolone is followed by a subsequent 17,20-lyase
transformation to dehydroepiandrosterone (DHEA) as the dominant pathways to cortisol precursors or
androgens in humans, respectively. How P450c17 regulates these two redox reactions is of special interest.
There is a paucity of direct electrochemical studies on steroidogenic P450s, and in this minireview
we provide an overview of these studies with P450c17. Historical consideration as to the difficulties
in obtaining reliable electrochemistry due to issues of handling proteins on an electrode, together
with advances in the electrochemical techniques are addressed. Recent work using Fourier transformed
alternating current voltammetry is highlighted as this technique can provide both catalytic information
simultaneously with the underlying redox transfer with the P450 haem.
