Abstract

Present Letter describes dynamics of FAD in non-aqueous and aqueous reverse micelles (RMs). FAD in non-aqueous reverse micelles (containing MeOH, glycerol, formamide or DMF) shows a prominent rise of quantum yield with increasing solvent loading, whereas in water RM FAD shows a rise in quantum yield only up to w0 = 10 and afterwards drops sharply up to bulk. A relative difference in polarity of dry AOT to solvent loaded RMs can be attributed to the opposite trend of changes in emission. This Letter of FAD in different RMs and its preferential orientation might be useful for understanding FAD dynamics inside flavoproteins.
