Specific recognition of Rpl8 by NO66. (a) A surface representation of the active site of NO66 is shown. Positively charged, negatively charged and neutral areas are shown in blue, red and white, respectively. The Rpl8204–224 peptide adopts a U-shaped conformation in the active site of NO66. (b) A detailed view of the interaction network of NO66 with Rpl8204–224 and NOG. Rpl8204–224 and the amino-acid residues of NO66 interacting with Rpl8204–224 are shown as stick models. Ni2+ and water molecules are shown as spheres. NO66, Rpl8204–224, NOG, Ni2+ and water molecules are coloured grey, yellow, green, magenta and red, respectively. (c) His216 is the hydroxylation site in Rpl8 catalyzed by NO66. The distances between the Cβ atoms of His216 and His218 and the Ni2+ ion in the active site are shown.
