Crystallographic studies of the complex of human HINT1 protein with a non-hydrolyzable analog of Ap4A

International journal of biological macromolecules 87, 62 - 69(2016). doi:10.1016/j.ijbiomac.2016.02.047
Histidine triad nucleotide-binding protein 1 (HINT1) represents the most ancient and widespread branch in the histidine triad proteins superfamily. HINT1 plays an important role in various biological processes, and it has been found in many species. Here, we report the first structure (at a 2.34 Å resolution) of a complex of human HINT1 with a non-hydrolyzable analog of an Ap4A dinucleotide, containing bis-phosphorothioated glycerol mimicking a polyphosphate chain, obtained from a primitive monoclinic space group P21 crystal. In addition, the apo form of hHINT1 at the space group P21 refined to 1.92 Å is reported for comparative studies.
