TOPICS: 

 

Topics (in order of presentation):  

  1. Force Fields: Atom types, force fields for proteins, DNA, organic and inorganic compounds: AMBER, CHARMM, MM3, UFF
  2. Partial Atomic Charges: Concepts and use in force fields, electronegativity, Gasteiger-Marsili charges, Electrostatic potential derived charges, constraints, differences in the CHARMM, AMBER, and MM2 force fields.
  3. Minimization Algorithms: local, global, with and whithout the use of gradients, DFP, eigenvector following, simplex, simulated annealing, genetic algorithms
  4. Solvent Models in Force Fields: explicit and implicit water models, OPLS force field, Generalized Born Model, Poisson-Boltzmann, Ewald Summation.
  5. Scoring Functions for Docking: Energy-based vs. knowledge-based scoring, estimation of entropic contributions and desolvation, DrugScore, consensus scoring.
  6. Conformational Search: conf. space, systematic search, tree search, random and stochastic search, distance geometry.
  7. Interpreting X-Ray Structures of Proteins: The .pdb file format, resolution, temperature factors, synchrotron scattering, crystal cells.
  8. Generation of 3D Molecular Structures: 3D coordinates from scratch, CORINA, CONCORD, knowledge-based approaches.
  9. Superpositioning of molecules: Optimum alignment of (rigid) 3D-structures, Kapsch algorithm, RMSD and other distance criteria.
  10. Assigning hydrogens to molecules, protonation states: general rules for valencies, titratable groups, change of protonation state due to interactions within a binding pocket.
  11. Hydrogen-bond networks in proteins: Finding the optimal interactions between protein residues, flip of side chains within proteins, assigning of corresponding polar hydrogens to X-ray structures. Comparison with the programs GRID and WHATIF.
  12. Maximum common substructure: Clique detection, colored graphs, reduced graphs.
