Fig. 3. Stereo representation of the Gcdα dimer with differently coloured domains. The N-terminal domain of monomer A is shown in yellow, the C-terminal domain is displayed semitransparently in grey, the N-terminal domain of monomer B is shown in green and the C-terminal domain in blue. The glutaconyl-CoA molecules in the two substrate-binding pockets of the dimer are drawn as stick models.
