X-RAY crystallographic studies on the complex of carboxypeptidase A with the inhibitor using alpha-nitro ketone as the zinc-binding groupX-RAY crystallographic studies on the complex of carboxypeptidase A with the inhibitor using alpha-nitro ketone as the zinc-binding group
Structural highlights
FunctionCBPA1_BOVIN Carboxypeptidase that catalyzes the release of a C-terminal amino acid, but has little or no action with -Asp, -Glu, -Arg, -Lys or -Pro (By similarity). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedZinc-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. Characterization of alpha-nitromethyl ketone as a new zinc-binding group based on structural analysis of its complex with carboxypeptidase A.,Wang SF, Tian GR, Zhang WZ, Jin JY Bioorg Med Chem Lett. 2009 Sep 1;19(17):5009-11. Epub 2009 Jul 12. PMID:19646864[1] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. See AlsoReferences
