Figure 6.
Stereo view of the glutaconyl binding site displayed with
amino acid residues within 4 Å of the crotonyl-CoA
product. Residues of the N- and C-terminal domains of GcdA are
colored blue and gray, respectively. Structurally equivalent
residues of A. fermentans GcdA are displayed in orange.
Non-conserved residues are marked with orange labels. The dashed
lines indicate hydrogen bonds.
