Figure 1.
Figure 1 Ribbon diagram of the crystal structure of TtPEPCK. The asymmetric unit of the ATP-liganded form comprising the A chain with closed conformation (blue and light blue) and the B chain with open conformation (red and pink) is shown. The N- and C-terminal domains are distinguished by dark and light colours, respectively. Bound calcium ions are depicted as green spheres. ATP, phosphate ions and glycerol molecules are depicted as stick models.
