Kinetic Mechanism of Glutaryl-CoA Dehydrogenase

Glutaryl-CoA dehydrogenase (GCD) is a homotetrameric enzyme containing one noncovalently bound FAD per monomer that oxidatively decarboxylates glutaryl-CoA to crotonyl-CoA and CO2. GCD belongs to the family of acyl-CoA dehydrogenases that are evolutionarily conserved in their sequence, structure, and function. However, there are differences in the kinetic mechanisms among the different acyl-CoA dehydrogenases. One of the unanswered aspects is...
