Improving Protein Docking Using Sustainable Genetic Algorithms

چکیده
Computational docking of ligands to protein structures is a key step in identifying potential drug candidates. The docking problem has been formulated into a ligand-protein binding energy optimization problem. Dozens of programs have been developed for molecular docking [1-9]. In any docking scheme, two requirements must be balanced: to get better precision with lower binding energy and to minimize the computational time. Recently, there is significant progress in computational protein docking [10]. The first type of new docking programs utilizes Fast Fourier Transformation (FFT) for efficient sampling of the conformation spaces [1;11-14]. The second type of programs exploits biochemical knowledge of the docking process to improve the docking performance. These include docking algorithms that use shape or physicochemical complementarily information [4;15;16] and predicted binding site information [17]. Another category of new docking algorithms are focused on improving the energy/potential function used for docking [18-22]. Finally, since the first successful application of genetic algorithms for protein docking, there has been significant progress in the global optimization field. New optimization algorithms such as spider-search [23], hybrid GA [24;25], differential evolution [26] have all been successfully applied to a variety of engineering problems. This paper followed this trend to apply new sustainable genetic algorithms to the protein docking problem.

MOTIVATION Protein-protein complexes are known to play key roles in many cellular processes. However, they are often not accessible to experimental study because of their low stability and difficulty to produce the proteins and assemble them in native conformation. Thus, docking algorithms have been developed to provide an in silico approach of the problem. A protein-protein docking procedure t...
متن کاملComparing Bound and Unbound Protein Structures for Investigating Flexibility
Fast methods for volume based Protein-Protein docking exist (eg. [1] or [4]). However, they employ the rigid-body assumption, and often miss the correct solution. To enhance todays docking algorithms the "induced fit" (comformational changes of a protein during the docking process) must be handled. Flexibility studies can help improving docking algorithms. Flexibility can be considered by enume...
