May function as a flavin mononucleotide (FMN)-dependent alkene reductase on substrates carrying alpha,beta-unsaturated carbonyl groups (ketones, aldehydes, carboxylic acids, esters, lactones or cyclic imides). [1] During the catalytic cycle, a reversible interconversion of the oxidized (FMN), semiquinone (FMNH•), and reduced (FMNH2) forms occurs in the various oxidoreductases. In its role as blue-light photo receptor, (oxidized) FMN stands out from the 'conventional' photo receptors as the signaling state and not an E/Z isomerization. FMN is then converted to flavin adenine dinucleotide (FAD) by the action of FAD pyrophosphorylase with ATP. FMN is a stronger oxidizing agent than NAD and is particularly useful because it can take part in both one- and two-electron transfers. Tissues differ as much as 1Bfold in their concentrations of FAD1 and FMN (1) and probably, therefore, in their total content of flavin enzymes. FMN ist ein stärkeres Oxidationsmittel als NAD und ist Teil solcher Reaktionen, in denen nicht nur Transfers von Hydridionen (also zwei Elektronen), sondern Einzelelektronenübertragungen stattfinden.
