Crystal structures of Cathepsin S inhibitor complexes

The structure was published by Pauly, T.A., Sulea, T., Ammirati, M., et al., Menard, R., Cygler, M., and Rath, V.L., in 2003 in a paper entitled "Specificity determinants of human cathepsin s revealed by crystal structures of complexes." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2003.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of Cathepsin S. This molecule has the UniProt identifier P25774 (CATS_HUMAN)search. The sample contained 217 residues which is < 90% of the natural sequence. Out of 217 residues 217 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule is most likely monomeric.
