The overall structure of AtEPSPS. Secondary structure elements are colored coral (helices), blue (strands) and gray (coil). Boundaries of the terminal and central domains are indicated in panel A, whereas panels B and C present rotated views over the respective domains. 310 helices are labeled as “η”. Approximate three-fold symmetry axes are normal to the viewing plane in panels B and C.
