Redox titration of flavoproteins allows to detect and analyze (1) the determinants of the stabilization of individual redox forms of the flavin by the protein; (2) the binding of the redox-active cofactor to the protein; (3) the effects of other components of the systems (such as micro- or macromolecular interactors) on parameters 1 and 2; (4) the pattern of electron flow to and from the flavin cofactor to other redox-active chemical species, including those present in the protein itself or in its physiological partners.

Abstract

Redox titration of flavoproteins allows to detect and analyze (1) the determinants of the stabilization of individual redox forms of the flavin by the protein; (2) the binding of the redox-active cofactor to the protein; (3) the effects of other components of the systems (such as micro- or macromolecular interactors) on parameters 1 and 2; (4) the pattern of electron flow to and from the flavin cofactor to other redox-active chemical species, including those present in the protein itself or in its physiological partners. This overview presents and discusses the fundamentals of the methodological approaches most commonly used for these purposes, and illustrates how data may be obtained in a reliable way, and how they can be read and interpreted.
