(a) Backbone superposition of the ensemble of 20 structures calculated for Mt-RubB on the structure closest to the average. The 21-residue N-terminal tag has been removed for clarity. (b) Cartoon representation of the structure closest to the average structure. The β-strands are colored blue, the 310-helix is colored orange, the zinc ion is colored magenta and the side-chain and main-chain atoms are shown for the four cysteine residues that coordinate the metal. |
