Structural biology insight regarding the binding mode of protein kinase inhibitors is valuable for the design of molecules possessing superior selectivity, efficacy and tolerability.
The generation and evaluation of molecular complexes in order to predict binding modes of protein ligand complexes, is still a challenging task.
Liebschner, D. et al. Elucidation of the phosphate binding mode of DING proteins revealed by subangstrom X-ray crystallography.
Although most of the drugs commercially available have emerged through conventional drug discovery methods such as high-throughput screening (HTS), computational methods and functional assays, it is the structural information provided by the three-dimensional (3D) atomic structures that discloses details regarding the binding mode of such proteins.
As reported in the review article by Luscombe et al. [ 30], protein-DNA interactions can be grouped into eight different structural/functional groups based on the structures of the DNA-binding region in the proteins, which is also referred to as the binding mode of the protein [ 30- 32].
In this study, a reliable 3D structure for transmembrane (TM) region of mouse TRESK (mTRESK) was constructed, and then the reasonable blocker binding mode of the protein was investigated.
When the binding mode of the protein is unclear, we recommend trying the parameter sets for sharp and broad peaks.
This is unlike the ATP binding mode of typical protein kinases (18), which use the conserved, ATP-binding motif GxGxxGxV (x, any amino acid), not found in PI3KCs and PI3K-related kinases.
Analysis of the binding mode of NADH and NADPH in proteins has shown that NADH-specific enzymes exhibit a few common features.
The Surflex-Dock program was used for the docking calculations and MOLCAD surfaces were generated for visualizing the binding mode of the docked protein-ligand complexes.
