CRYSTAL STRUCTURE OF HUMAN PROCATHEPSIN B AT 3.3 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
2PBH is a Single protein structure of sequence from Homo sapiens. Active as Cathepsin B, with EC number 3.4.22.1 Full crystallographic information is available from OCA.
Reference
Crystal structures of human procathepsin B at 3.2 and 3.3 Angstroms resolution reveal an interaction motif between a papain-like cysteine protease and its propeptide., Turk D, Podobnik M, Kuhelj R, Dolinar M, Turk V, FEBS Lett. 1996 Apr 22;384(3):211-4. PMID:8617355
