Glutaryl-CoA dehydrogenase

Function

Glutaryl-CoA dehydrogenase (GCD) converts glutaryl-CoA to crotonyl-CoA. GCD is part of the metabolism of lysine and tryptophan^[1].

Disease

Defective GCD causes the often fatal glutaric acidemia^[2]. The active GCD is a tetramer. Mutations which result in GCD dimers or monomers are associated with glutaric acidemia.

Structural highlights

GCD active site is in a cleft formed by its α,β,α domains^[3].
