Structure and Mechanism of PhdC, a Prenylated‐Flavin Maturase
Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Prenylated flavin mononucleotide (prFMN) is a modified flavin cofactor required by the UbiD family of (de)carboxylase enzymes. While the reduced prFMNH2 form is produced by the flavin prenyltransferase UbiX, the corresponding two‐electron oxidized prFMNiminium form is required to support UbiD catalysis. Thus, oxidative maturation of prFMNH2 is

This chapter deals with enantioselective organocatalytic cycloaddition reactions. Several cinchona alkaloids have been recently demonstrated as efficient chiral organocatalysts for enantioselective Diels−Alder reactions. Thus, excellent results were obtained for the Diels−Alder reaction of 3-vinylindoles with maleimides catalysed by a ...
