Monitoring of artificial enzyme membrane systems by electric currents. I. Analytical treatment with direct current and buffered conductivity.


Continuous electric fields (E) modify the transport flows and the intramembrane concentration profiles of protons or of ionic substrates or cofactors (inhibitors). These "mediators' induce variations in enzyme activity, quantifiable by a generalized Damköhler group II psi distinguishing electrotransport reactions from diffusion reactions. For three typical… (More)
