systems simulation time starting structure apo protein 100 ns X-ray structure of HCV NS3/4A protein (PDB ID code 1CU1) inhibitor bound protein 100 ns X-ray structure of HCV NS3/4A protein complexed wi... h inhibitor (PDB ID code 4B73) apo protein (truncated) 100 ns removal of the six C-terminal residues from apo protein inhibitor bound protein(truncated) 100 ns removal of the six C-terminal residues from protein complexed with inhibitor All the structures were then modeled by using the program LEaP embedded in AMBER10  with the standard AMBER03 force field  for protein, including adding all missing hydrogen atoms of the protein.
The simulations of the X-ray crystal structure of 1CU1  and 4B73  were designed to prove the importance of the stability of an autoinhibited form of HCV NS3/4A protein by a small molecular binding at the novel allosteric site.
As shown in Table 1 , the truncated forms of HCV NS3/4A protein models were created by in silico removing the six C-terminal residues coordinates starting from above structures 1CU1 and 4B73.
