The semi-flexible docking studies were performed in order to understand the interaction between the recombinant Kringle 1 domain of human plasminogen and five ligands[ε-aminocaproic acid(EACA),trans-4-(aminomethyl) cyclohexane-1-carboxylic acid(AMCHA),L-lysine(Lys),7-aminoheptanoic acid(7-AHA) and benzylamine] by means of ABEEMσπ/MM.The results show that the simulated structure is very close to the crystal structure.The calculated binding energies of the five complexes are in the order of AMCHA>EACA>7-AHA>L...
