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