THROMBIN INHIBITOR FROM TRIATOMA PALLIDIPENNIS
Overview
Triabin, a 142-residue protein from the saliva of the blood-sucking, triatomine bug Triatoma pallidipennis, is a potent and selective thrombin, inhibitor. Its stoichiometric complex with bovine alpha-thrombin was, crystallized, and its crystal structure was solved by Patterson search, methods and refined at 2.6-A resolution to an R value of 0.184. The, analysis revealed that triabin is a compact one-domain molecule, essentially consisting of an eight-stranded beta-barrel. The eight strands, A to H are arranged in the order A-C-B-D-E-F-G-H, with the first four, strands exhibiting a hitherto unobserved up-up-down-down topology. Except, for the B-C inversion, the triabin fold exhibits the regular up-and-down, topology of lipocalins. In contrast to the typical ligand-binding, lipocalins, ... [(full description)]
