STRUCTURE OF THE PRODUCT COMPLEX OF ACETYL-ALA-PRO-ALA WITH PORCINE PANCREATIC ELASTASE AT 1.65 ANGSTROMS RESOLUTION
Overview
A single crystal of porcine pancreatic elastase was mounted in a thin-walled capillary and allowed to react with acetyl-Ala-Pro-Ala-paranitroanalide. Diffraction data to 1.65 A resolution were measured and the isomorphous structure was solved from the difference Fourier map. The structure contains two surprises. Two molecules of the product: acetyl-Ala-Pro-Ala molecule are bound in the extended binding site. Both molecules are bound backwards with respect to the established mode of peptide binding.
About this Structure
