3h7d Summary


The crystal structure of the cathepsin K Variant M5 in complex with chondroitin-4-sulfate

The structure was published by Cherney, M.M., Lecaille, F., Kienitz, M., et al., Li, Z., James, M.N., and Bromme, D., in 2011 in a paper entitled "Structure-activity analysis of cathepsin K/chondroitin 4-sulfate interactions." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.242 Å and deposited in 2009.

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