TRANSTHYRETIN (ALSO CALLED PREALBUMIN) COMPLEX WITH 3',5'-DINITRO-N-ACETYL-L-THYRONINE
OverviewOverview
The molecular structures of two human transthyretin (hTTR, prealbumin), complexes, co-crystallized with thyroxine, (3,5,3',5'-tetraiodo-L-thyronine; T(4)), and with, 3',5'-dinitro-N-acetyl-LL-thyronine (DNNAT), were determined by X-ray, diffraction methods. Crystals of both structures are orthorhombic, space, group P2(1)2(1)2, and have two independent monomers in the asymmetric unit, of the crystal lattice. These structures have been refined to 17.0% for, 8-2.0 A resolution data for the T(4) complex (I), and to R = 18.4% for, 8-2.2 A resolution data for the DNNAT structure (II). This report provides, a detailed description of T(4) binding to wild-type hTTR at 2.0 A, resolution, as well as DNNAT. In both structures, the two independent, hormone-binding sites of the TTR tetramer are ... [(full description)]
