CRYSTAL STRUCTURE OF HUMAN CATHEPSIN X

The structure was published by Guncar, G., Klemencic, I., Turk, B., et al., Karaoglanovic-Carmona, A., Juliano, L., and Turk, D., in 2000 in a paper entitled "Crystal structure of cathepsin X: a flip-flop of the ring of His23 allows carboxy-monopeptidase and carboxy-dipeptidase activity of the protease." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.67 Å and deposited in 2000.

The experimental data on which the structure is based was not deposited.
