Figure 1.

The crystal structure of LldR in complex with co-purified Zn²⁺. (A) Ribbon representation of the LldR-Zn²⁺ complex in a monomer. The ribbon model is coloured according to the sequence from blue at the N-terminus to red at the C-terminus, and the co-purified zinc ion is shown as a pink ball. (B) Ribbon representation of the LldR-Zn²⁺ dimer. The two monomers are coloured cyan and blue. (C) Close-up view of the Zn²⁺ binding site. The amino acid residues and a water molecule binding to Zn²⁺ are shown as sticks and a cyan ball, respectively. The figures were produced using PyMOL (DeLano Scientific LLC, http://pymol.sourceforge.net).
