Figure 1. The crystal structure of the hE3 homodimer. Shown is a stereo ribbon diagram of the dimer. The atoms from the FAD and NADH are shown as spheres. In the left monomer, the domains are differently colored: the FAD-binding domain is green; the NAD^+-binding domain, purple; the central domain, blue; the interface domain, orange. The other monomer is colored tan. Bound molecules of FAD and NADH are colored brown and cyan, respectively, for the left monomer, and tan in the right monomer.
