EIDs refer to transmissible . AutoDock Vina is an open-source program for doing molecular docking. Molecular docking is an established computational structure-based method used in drug discovery. The essence of molecular docking is a process of mutual recognition between two or more molecules, which involves spatial matching and energy matching between molecules. The interactions between proteins and other molecules play important roles in various biological processes, including gene transcription and expression, metabolic regulation, signal transduction, and cell communication. The molecular docking approach can be used to investigate interaction between a small molecule and a protein at the atomic level, which allow us to understan. Molecular docking may be defined as an optimization problem, which would describe the "best-fit" orientation of a ligand that binds to a particular protein of interest. Docking is a computational procedure of searching for an appropriate ligand that fits both energetically and geometrically the protein's binding site.

Over the years, it has been modified and improved to add new functionalities, and multiple engines have been developed. molecular docking is to place the ligand molecule at the active site of the receptor, and then evaluate the interaction between the ligand and the receptor in real time according to the principles of geometric complementarity, energy complementation, and chemical environment complementation, and find the relationship between the two molecules and Knowledge of the preferred orientation in turn may be used to predict the strength of association or binding affinity between two molecules using, for example, scoring functions. Molecular docking computationally predicts the conformation of a small molecule when binding to a receptor. It was originally designed and implemented by Dr. Oleg Trott in the Molecular Graphics Lab (now CCSB) at The Scripps Research Institute. Molecular Docking Training & Certification is a self-learning course designed to learn various types of docking. Information of the preferred orientation in turn may be used to predict the strength of binding affinity between a drug target and ligand molecule using scoring functions ( Lengauer & Rarey, 1996 ). Molecular docking is a type of bioinformatic modeling, an essential tool in structural molecular biology and in drug design. The first step for molecular docking is the preparation of protein structure; the most widely adopted practice is simply to remove all the solvent molecules, ions and other small molecular ligands, leaving an entirely empty binding pocket for docking.
