Appl. No.:

16/246246

Inventors:

- Pasadena CA, US
Eric M. Burstad - Durham NC, US
Frances H. Arnold - La Canada CA, US

Jared C. Lewis - Chicago IL, US

Assignee:

California Institute of Technology - Pasadena CA

International Classification:

C12P 13/02
C12N 9/02
C12P 7/62

Abstract:

The present invention provides methods for catalyzing the conversion of an olefin to any compound containing one or more cyclopropane functional groups using heme enzymes. In certain aspects, the present invention provides a method for producing a cyclopropanation product comprising providing an olefinic substrate, a diazo reagent, and a heme enzyme; and admixing the components in a reaction for a time sufficient to produce a cyclopropanation product. In other aspects, the present invention provides heme enzymes including variants and fragments thereof that are capable of carrying out in vivo and in vitro olefin cyclopropanation reactions. Expression vectors and host cells expressing the heme enzymes are also provided by the present invention.
