REFINED CRYSTAL STRUCTURE OF HUMAN PROCATHEPSIN B AT 2.5 ANGSTROM RESOLUTION
Overview
A wild-type human procathepsin B was expressed, crystallized in two, crystal forms and its crystal structure determined at 3.2 and 3.3, Angstroms resolution. The structure reveals that the propeptide folds on, the cathepsin B surface, shielding the enzyme active site from exposure to, solvent. The structure of the enzymatically active domains is virtually, identical to that of the native enzyme [Musil et al. (1991) EMBO J. 10, 2321-2330]: the main difference is that the occluding loop residues are, lifted above the body of the mature enzyme, supporting the propeptide, structure.
About this Structure
