F1-G MODULE PAIR RESIDUES 1-91 (C83S) OF TISSUE-TYPE PLASMINOGEN ACTIVATOR (T-PA) (NMR, 298K, PH2.95, REPRESENTATIVE STRUCTURE)
Contents |
Overview
BACKGROUND: The thrombolytic serine protease tissue-type plasminogen, activator (t-PA) is a classical modular protein consisting of three types, of domain in addition to the serine protease domain: F1 (homologous to, fibronectin type I); G (epidermal growth factor-like) and kringle., Biochemical data suggest that the F1 and G modules play a major role in, the binding of t-PA to fibrin and to receptors on hepatocytes. RESULTS: We, have derived the solution structure of the F1 and G pair of modules from, t-PA by two- and three-dimensional NMR techniques, in combination with, dynamical simulated annealing calculations. We have also obtained, information about the molecule's backbone dynamics through measurement of, amide 15N relaxation parameters. CONCLUSIONS: Although the F1 and G, modules each adopt their expected tertiary structure, the modules interact, intimately to bury a hydrophobic core, and the inter-module linker makes, up the third strand of the G module's major beta-sheet. The new structural, results allow the interpretation of earlier mutational data relevant to, fibrin-binding and hepatocyte-receptor binding.
