We address methodological issues in quantum mechanics/molecular mechanics (QM/MM) calculations on a zinc-dependent enzyme. We focus on the first stage of peptide bond cleavage by matrix metalloproteinase-2 (MMP-2), that is, the nucleophilic attack of the zinc-coordinating water molecule on the carbonyl carbon atom of the scissile fragment of the substrate.(More)
The mechanism of enzymatic peptide hydrolysis in matrix metalloproteinase-2 (MMP-2) was studied at atomic resolution through quantum mechanics/molecular mechanics (QM/MM) simulations. An all-atom three-dimensional molecular model was constructed on the basis of a crystal structure from the Protein Data Bank (ID: 1QIB), and the oligopeptide(More)
