Description
Summary:Anion-π interactions are commonly attributed to electrostatic forces between an anion and the electropositive region at the π-face of an electron-deficient arene. The authors present a multiapproach theoretical analysis which indicates that anion-flavin interactions operating in flavoproteins are not purely electrostatic but involve a substantial charge-transfer component. This finding sheds new light at the regulation of the redox properties of the co-factors FAD and FMN, and suggests that anion-π interactions should not be considered as generally noncovalent.
