Publication Abstract from PubMed

The structure of the complex of Aeromonas proteolytica aminopeptidase, a two-zinc exopeptidase, with the inhibitor p-iodo-D-phenylalanine hydroxamate has been determined by X-ray crystallography. Refinement of the structure, which includes 220 water molecules, using data at 0.80-0.23-nm resolution resulted in a crystallographic residual R value of 16%. The hydroxamate group adopts a planar conformation whereby the two oxygen atoms interact with the zinc ions. The N-hydroxyl group of the inhibitor is located between the two zinc ions, a position which is close to that occupied by a water molecule in the native structure. The carbonyl oxygen of the inhibitor binds to Zn1, which becomes pentacoordinated while Zn2 remains tetracoordinated, in contrast to the native protein where both zinc ions were shown to be tetracoordinated and structurally equivalent. Interactions of the carboxylate oxygens of Glu151 with the hydroxamate group play an important role in the stabilization of the complex.

The structure of the Aeromonas proteolytica aminopeptidase complexed with a hydroxamate inhibitor. Involvement in catalysis of Glu151 and two zinc ions of the co-catalytic unit.,Chevrier B, D'Orchymont H, Schalk C, Tarnus C, Moras D Eur J Biochem. 1996 Apr 15;237(2):393-8. PMID:8647077^[1]
