Abstract:
The high-performance workspace for protein conformational modeling is discussed. There are three stages of the calculations in the workspace: 1) Protein conformational modeling 2) Docking conformations 3) Interaction analysis The workspace were used for calculations of abl kinase and its mutants conformational properties. The docking and interaction analysis of imatinib, niloatinib and dasatinib were done. In silico experiments show that free binding energy decreases for interactions with mutants. Distributed workspace architecture based on CLAVIRE platform provides flexible tuning for wide range of problems such as homology modeling, docking, rescoring and combining them in workflows. Besides that, Distributed workspace architecture based on CLAVIRE platform provides high potential for scalability in heterogeneous computing environments.
