CRYSTAL STRUCTURE OF WILD TYPE HUMAN PROCATHEPSIN K

The structure was published by Sivaraman, J., Lalumiere, M., Menard, R., and Cygler, M., in 1999 in a paper entitled "Crystal structure of wild-type human procathepsin K." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.2 Å and deposited in 1998.

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

This PDB entry contains multiple copies of the structure of PROTEIN (PROCATHEPSIN K).
