▼a We developed two enhanced sampling methods, one for configurational sampling of small molecules/peptides, and the other for calculating protein-protein binding free energies to solve interaction/recognition problems.To enhance the configurational sampling which can be very computationally demanding with conventional Molecular Dynamics (MD) simulations, a Hybrid non-equilibrium MD/Monte Carlo propagator is developed in which we apply non-equilibrium work to the system in order to boost the Hamiltonian while a Metropolis-Hastings Monte Carlo (MC) step ensures sampling from the correct Boltzmann distribution. When the sampling of a biomolecular system gets stuck in a kinetic trap (metastable state), the Hybrid neMD/MC propagator helps it to escape. Specific biomolecular peptide systems were used to test validity and performance of the method.We put forth a novel theoretical framework for binding free energy calculations between two proteins, leaning on the optimal curvilinear minimum free-energy path (MFEP) determined from the string method. The curvilinear path connects the fully bound state to the unbound state and is generated from quick simulations using an implicit solvent model, followed by application of the dynamic histogram analysis method (DHAM). In each of the simulations DHAM finds the free energy minimum |
