Abstract

Cytochrome P450 enzymes (P450) have the potential to be useful in many industries, including applications in pharmaceuticals, pesticides, fragrances and more. P450’s catalytic cycle is reliant on NAD(P)H to function which is expensive and degrades during long term storage. Ultimately, we seek to replace NAD(P)H with a comparable, cheaper and more effective system using cobaltocenium derivatives as substitutes. Our cobaltocenium product functions as a mediator is to transfer electrons from an electrode to the protein in order to create a new and complete electrochemical system. This project is made up of four parts. First, we synthesize our cobaltocenium derivatives. Then we alter our protein and quantify the synthesized protein. The protein development consists of replacing the naturally occuring thiol group with an azide group. Then the cobaltocenium derivative is attached via a “click” reaction. Quantification is done using ICP, UV-Vis, and fluorometric analysis. Finally electrochemical testing and catalytic testing test the effectiveness of the P450-cobaltocenium as an electron mediator.
