Abstract
A method for fluorescence detection of a protein’s redox state based on resonance energy transfer from an attached fluorescence label to the prosthetic group of the redox protein is described and tested for proteins containing three types of prosthetic groups: a type-1 copper site (azurin, amicyanin, plastocyanin, and pseudoazurin), a heme group (cytochrome c550), and a flavin mononucleotide (flavodoxin). This method permits one to reliably distinguish between reduced and oxidized proteins and to perform potentiometric titrations at submicromolar concentrations.
