Cathepsin K complexed with a constrained ketoamide inhibitor
The structure was published by Barrett, D.G., Boncek, V.M., Catalano, J.G., et al., Willard, D.H., Wright, L.L., and Zhou, H.Q., in 2005 in a paper entitled "P(2)-P(3) conformationally constrained ketoamide-based inhibitors of cathepsin K." (abstract).
This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2005.
The experimental data on which the structure is based was also deposited.
The PDB entry contains the structure of Cathepsin K. This molecule has the UniProt identifier P43235 (CATK_HUMAN). The sample contained 215 residues which is < 90% of the natural sequence. Out of 215 residues 213 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.
