| Research Abstract |
We examined the atomic and electronic mechanism underlying binding between zinc-containing proteins and a series of ligands, using the QM (Quantum mechanics)/MM (Molecular Mechanics) and ab initio FMO (Fragment Molecular Orbital) calculations and LERE (Linear Expression by Representative Energy terms)-QSAR (Quantitative Structure-Activity Relationship) procedure. As a result, the LERE-QSAR procedure demonstrated to quantitatively reveal differences in the binding mechanisms between the several cases involving similar but different zinc-containing proteins at the electronic and atomic levels.
