title: S-adenosylmethionine and radical-based catalysis.
abstract: S-adenosylmethionine is the major methyl donor in all living organisms, but it is also involved in many other reactions occurring through radical-based catalysis. The structure and function of some of these enzymes, including those involved in the synthesis of the molybdenum cofactors, biotin, lipoate, will be discussed.
