Bioelectrocatalysis by a selenoenzyme

Journal of Electroanalytical Chemistry, 1998
Electron transfer between the selenoprotein phospholipid hydroperoxide glutathione peroxidase and gold electrodes covered by a self assembled monolayer of mercaptoundecanoic acid was achieved for the first time. Selenenic acid, the oxidized enzyme form, which is generated by the reaction with peroxide, was not reduced at the electrode.

Graphene Carrier for Magneto‐Controllable Bioelectrocatalysis

Small, 2013
A magnetically driven fuel-free graphene carrier loaded with redox-active cargo-ferrocene as an electron mediator is fabricated for magneto-controllable bioelectrocatalysis. The activation and deactivation of redox-active cargo's redox activity by magnetically driven positioning of the graphene carrier with loaded ferrocene near and away from the ...

Bioelectrocatalysis of NAD+ reduction

Journal of Electroanalytical Chemistry, 1992
Abstract A thermokinetic approach to the catalysis of the electrochemical reduction of NAD + by the hydrogenase of Alcaligenes eutrophus H16 is presented. The influence of temperature is weak, with an activation energy of 18 kJ/mol, whereas classical NAD + hydrogenation with gaseous hydrogen shows an activation energy of 34 kJ/mol.

Principles of Bioelectrocatalysis

1980
By bioelectrocatalysis we mean the association of enzymatic (in general, biochemical) reaction with an electrochemical process. Schematically it can be shown as follows (1–4).

MET-Type Bioelectrocatalysis

2020
This chapter deals with theoretical features of MET-type bioelectrocatalysis with emphasis of steady-state serial reactions. The fundamental concept in the selection of mediators is described based on linear free energy relationship and diffusion-controlled kinetics.
