Acetone in Water: Electrostatic Interactions • AMBER10 MD package – Assisted Model Building with Energy Refinement – Package of molecular simula4on programs – Molecular mechanical force fields for the simula4on of biomolecules (amino acids, protein, nuclei acids, ...) – Prepara4on: antechamber • program suite to automate the process of developing force field descriptors for most organic molecules – Prepara4on: XLEaP • basic model building and Amber coordinate and parameter/topology input file crea4on • includes a molecular editor which allows for building residues and manipula4ng molecules – Simula4on: sander • simulated annealing with NMR-‐derived energy restraints • also main program used for MD simula4ons
Antechamber – automates the process of developing force field descriptors for most organic molecules. – reads the electrosta4c grid from a Gaussian log file and calculates RESP (Restrained ElectroSta4c Poten4al fit) charges.
