Crystal Structure of Cathepsin B from T. brucei in complex with CA074

The structure was published by Kerr, I.D., Wu, P., Marion-Tsukamaki, R., Mackey, Z.B., and Brinen, L.S., in 2010 in a paper entitled "Crystal Structures of TbCatB and rhodesain, potential chemotherapeutic targets and major cysteine proteases of Trypanosoma brucei" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.6 Å and deposited in 2009.

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

This PDB entry contains multiple copies of the structure of Cathepsin B-like cysteine protease.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
