31. Temperature Dependence of the Formal Reduction Potential of Putidaredoxin
Published: 7/20/2000
Authors: Vytautas Reipa, Marcia J Holden, M P. Mayhew, V L. Vilker
Abstract: Putidaredoxin (Pdx), a [2Fe-2S] redox protein of size M^dr^ transfers two electrons in two separate steps from the flavin containing putidaredoxin reductase to the heme protein, cytochrome CYP101 in the P450cam catalytic cycle. It has recently come ...

32. Improving the Cytochrome P450 Enzyme System for Electrode-Driven Biocatalysis of Styrene Epoxidation
Published: 7/1/2000
Authors: M P. Mayhew, Vytautas Reipa, Marcia J Holden, V L. Vilker
Abstract: 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 substra ...

33. Variation in the Formal Reduction Potential of an (2FE-2S) Iron-Sulfur Protein and its Mutants
Published: 5/1/2000
Authors: V L. Vilker, Vytautas Reipa, Marcia J Holden, M P. Mayhew
Abstract: 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 cofa ...

34. Differential Surface Stress of a Tin Oxide Electrode
Published: 4/1/2000
Authors: Gintaras Valincius, Vytautas Reipa
Abstract: 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 relat ...

35. Surface stress of tin oxide electrode
Published: 1/1/2000
Authors: Gintaras Valincius, Vytautas Reipa

36. Reorientation of Tetradecylmethylviologen on Gold Upon Co-Adsorption of Decanethiol and its Medition of Electron Transfer to Nitrate Reductase
Published: 11/9/1999
Authors: Vytautas Reipa, S L Yeh, H G Monbouquette, V L. Vilker
Abstract: Decanethiol was coadsorbed with tetradecylmethyl viologen (C^d14^MV; 1-Methyl-1 -tetradecyl-4,4 -bipyridinium chloride) on gold electrodes in order to improve stability of C^d14^MV as an electrochemical mediator for coupling to nitrate reductase enzy ...

37. Challenges in Capturing Oxygenase Activity In Vitro
Published: 11/1/1999
Authors: V L. Vilker, Vytautas Reipa, M P. Mayhew, Marcia J Holden
Abstract: 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 clas ...

38. Combined Spectroscopic Ellipsometry and Voltammetry of Tetradecylmethyl-viologen Films on Gold
Published: 10/27/1998
Authors: Vytautas Reipa, H G Monbouquette, V L. Vilker

39. Stark Spectroscopy of Tryptamine Immobilized on a Gold Electrode
Published: 7/15/1998
Authors: Adolfas Kastytis Gaigalas, Vytautas Reipa, G. Niaura

40. A Direct-Electrode-Driven P450 Cycle for Biocatalysis
Published: 12/9/1997
Authors: Vytautas Reipa, M P. Mayhew, V L. Vilker
