Docking Program

Protein-ligand docking programs are indispensable tools for predicting the binding pose of a ligand to the receptor protein in current structure-based drug design. In this paper, we evaluate the performance of grey wolf optimization (GWO) in protein-ligand docking. Two versions of the GWO docking program – the original GWO and the modified one with random walk – were implemented based on AutoDock Vina. Our rigid docking experiments show that the GWO programs have enhanced exploration capability leading to significant speedup in the search while maintaining comparable binding pose prediction accuracy to AutoDock Vina. For flexible receptor docking, the GWO methods are competitive in pose ranking but lower in success rates than AutoDockFR. Successful redocking of all the flexible cases to their holo structures reveals that inaccurate scoring function and lack of proper treatment of backbone are the major causes of docking failures.

Protein T1R3, the main subunit of sweet, as well as amino acid, taste receptor, is expressed in the epithelium of the tongue and gastro intestinal tract, in β–cells of the pancreas, hypothalamus, and numerous other organs. Recently, convincing witnesses of T1R3 involvement in control of carbohydrate and lipid metabolism, and control of production of incretines and insulin, have been determined. In the study on Tas1r3-gene knockout mouse strain and parent strain C57Bl/6J as control, priority data concerning the effect of T1R3 on the morphological characteristics of Langerhans islets in the pancreas, are obtained. In Tas1r3 knockout animals, it is found that the size of the islets and their density in pancreatic tissue are reduced, as compared to the parent strain. Additionally, a decrease of expression of active caspase-3 in islets of gene-knockouts is demonstrated. The obtained data show that the lack of a functional, gene encoding sweet-taste receptor protein causes a dystrophy of the islet tissue and associates to the development of pathological changes in the pancreas specific to type-2 diabetes and obesity in humans.
