Title: Characterization of alpha-nitromethyl ketone as a new zinc-binding group based on structural analysis of its complex with carboxypeptidase A.
Authors: Wang SF, Tian GR, Zhang WZ, Jin JY.
Abstract: Zinc-binding groups (ZBGs) are exhaustively applied in the development of the new inhibitors against a wide variety of physiologically and pathologically important zinc proteases. Here the alpha-nitro ketone was presented as a new ZBG, which is a transition-state analog featured by the unique bifurcated hydrogen bonds at the active site of carboxypeptidase A based on the structural analysis. Introduction of a nitro group at the alpha-position of the ketone could provide more non-covalent interactions without loss of the abilities to form a tetrahedral transition-state analog.
