Molecular dynamics simulations of the drug-resistant M2 mutants, A30T, S31N, and L26I, were carried out to investigate the inhibition of M2 activity using amantadine (AMT). The closed and open channel conformations were examined via non- and triply protonated H37. For the nonprotonated state, these mutants exhibited zero water density in the conducting(More)
A molecular dynamics (MD) simulation based on a combined ab initio quantum mechanics/molecular mechanics (QM/MM) method has been performed to investigate the solvation structure and dynamics of H3O+ in water. The QM region is a sphere around the central H3O+ ion, and contains about 6-8 water molecules. It is treated at the Hartree-Fock (HF) level, while the(More)
