With approximately 1% of proteins being flavoproteins, flavins are at the heart of a plethora of redox reactions in all areas of biology. Thanks to a series of fascinating recent discoveries, in addition to redox chemistry, covalent catalysis is now being recognized more frequently as a common strategy in flavoenzymes, with unprecedented mechanisms becoming apparent. Thus, noncanonical covalent reactions by flavins are emerging as a new pervasive concept in basic enzymology and biochemistry. These diverse enzymes are engaged in most biological processes, positioning the knowledge being gained from these new mechanisms to be translated into drugs that function through covalent mechanisms.
