Abstract
The cytochrome P450 enzymes (CYPs) CYP-sb21 from Sebekia benihana and CYP-pa1 from Pseudonocardia autotrophica are able to hydroxylate the immunosuppressant cyclosporin A (CsA) in a regioselective manner, giving rise to the production of two hair-stimulating agents (with dramatically attenuated immunosuppressant activity), γ-hydroxy-N-methyl-l-Leu4-CsA (CsA-4-OH) and γ-hydroxy-N-methyl-l-Leu9-CsA (CsA-9-OH). Recently, the in vitro activity of CYP-sb21 was identified using several surrogate redox partner proteins. Herein, we reconstituted the in vitro activity of CYP-pa1 for the first time via a similar strategy. Moreover, the supporting activities of a set of ferredoxin (Fdx)/ferredoxin reductase (FdR) pairs from the cyanobacterium Synechococcus elongatus PCC 7942 were comparatively analyzed to identify the optimal redox systems for these two CsA hydroxylases. The results suggest the great value of cyanobacterial redox partner proteins for both academic research and industrial application of P450 biocatalysts.
