Crystal structure of Cathepsin K complexed with 7-Methyl-Substituted Azepan-3-one compound

The structure was published by Yamashita, D.S., Marquis, R.W., Xie, R., et al., Zembryki, D.L., Lark, M.W., and Veber, D.F., in 2006 in a paper entitled "Structure activity relationships of 5-, 6-, and 7-methyl-substituted azepan-3-one cathepsin K inhibitors." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.55 Å and deposited in 2006.

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