A serine-substituted P450 catalyzes highly efficient carbene transfer to olefins in vivo

Abstract

Whole-cell catalysts for non-natural chemical reactions will open new routes to sustainable production of chemicals. We designed a cytochrome 'P411' with unique serine-heme ligation that catalyzes efficient and selective olefin cyclopropanation in intact Escherichia coli cells. The mutation C400S in cytochrome P450_(BM3) gives a signature ferrous CO Soret peak at 411 nm, abolishes monooxygenation activity, raises the resting-state FeIII-to-FeII reduction potential and substantially improves NAD(P)H-driven activity.

Errata

In the version of this article initially published, the Protein Data Bank codes for the P450 and P411 constructs were inadvertently switched. Accession code 4H23 actually corresponds to the P411 structure, and 4H24 corresponds to the P450 structure. The error has been corrected in the HTML and PDF versions of the article.
