Noureddine Tchouar is currently a professor at the University of Sciences and technology of Oran. He received his PhD degrees in Chemical Physics from University of Sciences and technology of Oran. His research interests cover the areas of chemistry physics and computational chemistry. He studies the quantum properties of dense fluids with molecular dynamics simulation and recently his main interest is to develop QSAR models of biomolecules by means of theoretical and computational methods.


Abstract:

Molecular docking is a method that predicts the preferred orientation of one molecule to another from a stable complex for example enzyme-substrate complex. This is so important to study the preferred orientation of the molecules and may be used to predict the strength of association or binding affinity. This can be achieved using computer-aided molecular docking to create a reasonably accurate model of energy and must be able to deal with the combinatorial complexity incurred by the molecular flexibility of the docking partners. Molecular dynamics (MD) is a computer simulation method for studying the physical movements of atoms and molecules, throughout which we use enzymesenzyme as a model to define N-body simulation. The atoms and molecules are allowed to interact for a fixed period of time (nanosecond) giving a view of the dynamical evolution of the system. We will use program visualization ٍ(VMD)) to describe the fundamental aspect of analysis and data interpretation.
