Abstract		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 ŠMusil et al. (1991) EMBO J. 10, 2321-2330Ć: the main difference is that the occluding loop residues are lifted above the body of the mature enzyme, supporting the propeptide structure.
