==Crystal structure of auxin binding protein==
-
The structure of auxin-binding protein 1 (ABP1) from maize has been, determined at 1.9 A resolution, revealing its auxin-binding site. The, structure confirms that ABP1 belongs to the ancient and functionally, diverse germin/seed storage 7S protein superfamily. The binding pocket of, ABP1 is predominantly hydrophobic with a metal ion deep inside the pocket, coordinated by three histidines and a glutamate. Auxin binds within this, pocket, with its carboxylate binding the zinc and its aromatic ring, binding hydrophobic residues including Trp151. There is a single disulfide, between Cys2 and Cys155. No conformational rearrangement of ABP1 was, observed when auxin bound to the protein in the crystal, but examination, of the structure reveals a possible mechanism of signal transduction.
