Oxidation of amines by flavoproteins
Web) catalyze the oxidation of amines via an oxidative cleavage of the α-CH bond of the substrate to form an imine product with the concomitant reduction of the flavin cofactor (Fig. 1A). The imine product is then hydrolyzed (non-enzymatically in the cases investigated) to the corresponding aldehyde and ammonia (or amine for secondary or tertiary amine … WebThe flavoprotein d-amino acid oxidase has long served as a paradigm for understanding the mechanism of oxidation of amino acids by flavoproteins. Recently, a mutant d-amino acid oxidase (Y228L/R283G) that catalyzed the oxidation of amines rather than amino acids was described [Yasukawa, K., et al. (2014) Angew. Chem., Int. Ed. 53, 4428–4431].
