Control of Adenosylmethionine-Dependent Radical Generation in Biotin Synthase: A Kinetic and Thermodynamic Analysis of Substrate Binding to Active and Inactive Forms of BioB()

Biotin synthase (BS) is an AdoMet-dependent radical enzyme that catalyzes the insertion of sulfur into saturated C6 and C9 atoms in the substrate dethiobiotin. To facilitate sulfur insertion, BS catalyzes the reductive cleavage of AdoMet to methionine and 5′-deoxyadenosyl radicals, which then abstra...
