Olefin Cyclopropanation via Carbene Transfer Catalyzed by Engineered Cytochrome P450 Enzymes
Abstract
Putting a C in Cytochrome: Cytochrome P450 enzymes oxidize hydrocarbons using a highly reactive iron oxo intermediate. Much research has focused on tuning the protein structure to broaden the range of hydrocarbons that can be functionalized. Coelho et al. (p. 307 , published online 20 December; see the Perspective by Narayan and Sherman ) substituted a carbene source for the oxygen to make a P450 mutant a cyclopropanation catalyst whereby a carbon fragment is transferred in place of oxygen. Though carbene activation by iron is chemically analogous to the native oxygen activation pathway, the overall reaction is completely different from any known enzymatic transformation.

“In their first report [39••], Arnold and co-workers hypothesized that cytochrome P450 enzymes, which catalyze a variety of reactions involving oxene transfer, might also be capable of generating and promoting transfer of carbene intermediates in the presence of suitable reagents (Figure 3A).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
