Figure 2From: Crystal structures of a halophilic archaeal malate synthase from Haloferax volcanii and comparisons with isoforms A and GPossible domain swapping in H. volcanii MSH. The subunit of the trimer closest to the viewer is rendered in the same form and colors as in figure 1, with the C-terminal domain on the right. The C-terminal domain on the left, also rendered as a red cartoon ribbon trace would instead be connected to the green β8/α8 barrel if domain swapping occurs. In the domain swap the C-terminal domain connected to the barrel of one subunit (green) would be donated to complete the active site of the neighboring barrel shown as a blue surface rather than its own. The short disordered surface loops (372-380) are depicted as red dotted lines.Back to article page
