The 3D solution structure of wheat nonspecific lipid transfer protein (ns-LTP) complexed with prostaglandin B-2, a lipid with both vinyl and hydroxylated groups, has been determined by H-1 2D NMR. The global fold of the protein is close to the previously published structures of wheat, maize, barley and rice ns-LTPs. The Ligand is almost completely embedded in the hydrophobic core of the protein. Structure comparisons of free and bound wheat ns-LTP reveal that the binding of prostaglandin B-2 hardly affects the global fold of the protein. The structural data on this unusual complex are discussed and compared with other known ns-LTP lipid-complexes.
