QSite
A high-performance QM/MM program
Overview
QSite is a multi-scale simulation tool that utilizes the QM/MM method, which combines the principles of quantum mechanics and molecular mechanics. It is designed to accurately predict the molecular configurations, energetics, and the electronic structures of a reactive system through quantum chemical treatment of atoms, providing crucial insights into reactive chemistry essential for understanding chemical transformation in the presence of intermolecular interactions. QSite is equally applicable for describing non-reacting chemical systems.
Key Capabilities
High performance
Outperforms other QM/MM programs because it takes advantage of Jaguar, long recognized as the industry leader in QM calculations.
Advanced technology
Provides an innovative approach to the QM/MM interface specifically addressing protein systems and interactions between QM and MM regions.
Transition metal convergence
Achieves a high degree of accuracy in metalloproteins thanks to Jaguar’s advanced capabilities; it reliably and efficiently converges to the correct ground state of transition metal containing systems.
Wavefunction choices
Offers different levels of theory to evaluate the QM region: Hartree Fock, DFT, and local MP2. This allows the user to choose the best balance between computational cost and accuracy.
Advanced calculation setup and analysis
Automatically applies special interface parameters, making it simple to set up calculations. Computed results, such as molecular orbitals and electron densities, can be visualized within Maestro.
