Cryo-EM structure of Ldh-EtfAB complex from Acetobacterium woodii
 Ldh-EtfAB complex Ldh-EtfAB complex 0 1 2 3
Complex composed of a dimer of a trimer of EtfA, EtfB and Ldh subunits making a hexameric oligomer state. Each of the subunits contain 1 FAD co-factor making total of 6 FADs. 2 Ldh subunits contain 1 Fe molecule each.
