Improving the Cytochrome P450 Enzyme System for Electrode-Driven Biocatalysis of Styrene Epoxidation

July 1, 2000

Author(s)

M P. Mayhew, Vytautas Reipa, Marcia J. Holden, V L. Vilker

Cytochrome P450 enzymes catalyze a vast array of oxidative and reductive biotransformations that are potentially useful for industrial and pharmaceutical syntheses. Factors such as cofactor utilization and slow reaction rates for non-natural substrates

Variation in the Formal Reduction Potential of an (2FE-2S) Iron-Sulfur Protein and its Mutants

May 1, 2000

Author(s)

V L. Vilker, Vytautas Reipa, Marcia J. Holden, M P. Mayhew

We have been pursuing the detailed pathway by which cytochrome P450cam (CYP101) transfers electrons through a three diffusible protein subunit system, and how this system might be engineered to eliminate nonessential subunits and the costly NADH cofactor

Differential Surface Stress of a Tin Oxide Electrode

April 1, 2000

Author(s)

Gintaras Valincius, Vytautas Reipa

Differential surface stress measurements performed using estance technique and simultaneous measurements of the differential capacitance provide experimental evidence for deviation of n-tin oxide electrode's properties from the electrocapillary

Surface stress of tin oxide electrode

January 1, 2000

Reorientation of Tetradecylmethylviologen on Gold Upon Co-Adsorption of Decanethiol and its Medition of Electron Transfer to Nitrate Reductase

November 9, 1999

Author(s)

Vytautas Reipa, S L. Yeh, H G. Monbouquette, V L. Vilker

Decanethiol was coadsorbed with tetradecylmethyl viologen (C 14MV; 1-Methyl-1 -tetradecyl-4,4 -bipyridinium chloride) on gold electrodes in order to improve stability of C 14MV as an electrochemical mediator for coupling to nitrate reductase enzymes

Challenges in Capturing Oxygenase Activity In Vitro

November 1, 1999

Author(s)

V L. Vilker, Vytautas Reipa, M P. Mayhew, Marcia J. Holden

Biocatalysis using oxygenase or desaturase enzymes has the potential to add value to native fats and oils by adding oxygen hydroxyl groups, or double bonds to create regio- and/or stereospecific products. These enzymes are a subset of the large class of
