Characterization of P450 FcpC, the enzyme responsible for bioconversion of diosgenone to isonuatigenone in Streptomyces virginiae IBL-14.
A new cytochrome P450 monooxygenase, FcpC, from Streptomyces virginiae IBL-14 has been identified. This enzyme is found to be responsible for the bioconversion of a pyrano-spiro steroid (diosgenone) to a rare nuatigenin-type spiro steroid (isonuatigenone), which is a novel C-25-hydroxylated diosgenone derivative. A whole-cell P450 system was developed for the production of isonuatigenone via the expression of the complete three-component electron transfer chain in an Escherichia coli strain.
