Figure 5. Catalytic activity of spmoB proteins.
a, Epoxidation of propylene to propylene oxide expressed as a percentage of the activity of M. capsulatus (Bath) as-isolated, membrane-bound pMMO. b, Oxidation of methane to methanol expressed as a percentage of the activity of M. capsulatus (Bath) as-isolated, membrane-bound pMMO. All values are an average of at least two independent refolding preparations. The activities of the spmoB proteins were compared to activities of membrane-bound pMMO measured under the same experimental conditions.
