Functionalization of the cytochrome P450cam monooxygenase system.

Functionalization of the cytochrome P450cam monooxygenase system, which requires electron transfer among three different proteins, was successfully attained in the micro-scale aqueous compartments of stable water-in-oil (W/O) emulsions, which can be easily formed by mixing organic and aqueous solutions. The activity of the cytochrome P450 monooxygenase system as to hydroxylation of camphor, as a model, was efficiently improved through coupling of the system with the NADH regeneration process, as illustrated on the cover of this issue, suggesting the potential utility of the micro-scale cell-like aqueous compartments of W/O emulsions for practical multicomponent enzymatic reactions, especially for substrates with low aqueous solubility.
