Figure 2

Surface representation comparing the “open” to the “closed” ERAP1 and ERAP2 structures. Domains are colored as in figure 1. Cutaway views are shown to allow visualization of the internal cavity of the enzyme. The Zn(II) atom is shown in red. Notice how the internal cavity is open towards the solvent on the top-left edge of each figure.
