A cytochrome P-450 LM2 reconstituted system mediated expoxidations of small terminal alkenes to the corresponding alkyloxiranes. This oxidation was accompanied by a stereoselective proton exchange of the E proton. Propene was oxidized in D2O to trans-3-deuterio-2-methyloxirane, and E-1-deuteriopropene was epoxidized
