graphic file with name cdf291f3a.jpg — Fig. 3. Auxin binding to ABP1. (A) Omit electron density map at 1.9 Å resolution and contoured at 3σ revealing 1-NAA bound to ABP1. The view in (B) is rotated ∼60° around the x-axis compared with the view in (A), and His57, Glu63, Leu25 and Ile48 are omitted from this view for clarity. The bidentate binding of the 1-NAA carboxylate to the zinc (dark blue sphere) can be clearly seen, as can the hydrophobic environment of the naphthalene ring. (C) Simplified representation of the contacts between 1-NAA and ABP1 and between the zinc ion and ABP1 in the complex. Distances shown are in angstroms. (A) and (B) were prepared using BOBSCRIPT (Esnouf, 1997).
