FIG. 3.
(A) The URODBs dimer in the asymmetric unit. (B) Ribbon diagram of the URODBs monomer. (C) Superposition of Cα atoms for the monomer of UROD from B. subtilis (red), humans (blue), and tobacco (green), respectively. The L1 and L2 loops are marked. (D) Molecular surface colored (blue, positive; red, negative) according to the electrostatic potentials of the URODBs monomer. The areas of the L1 and L2 loops are denoted. The active-site cleft is located in the β-barrel. All colored images in this paper were generated in PYMOL (http://www.pymol.org).
