  • PubMed Abstract: 

    A general question in biochemistry is the interplay between the chemical properties of cofactors and the surrounding protein matrix. Here, the functions of NADP + and FAD are explored by investigation of a representative monooxygenase reconstituted with chemically-modified cofactor analogues. Like pieces of a jigsaw puzzle, the enzyme active site juxtaposes the flavin and nicotinamide rings, harnessing their H-bonding and steric properties to finely construct an oxygen-reacting center that restrains the flavin-peroxide intermediate in a catalytically-competent orientation. Strikingly, the regio- and stereoselectivities of the reaction are essentially unaffected by cofactor modifications. These observations indicate a remarkable robustness of this complex multi-cofactor active site, which has implications for enzyme design based on cofactor engineering approaches.
