Structure of Oligopeptidase B from Leishmania major

The structure was published by Mcluskey, K., Paterson, N.G., Bland, N.D., Isaacs, N.W., and Mottram, J.C., in 2010 in a paper entitled "Crystal Structure of Leishmania Major Oligopeptidase B Gives Insight Into the Enzymatic Properties of a Trypanosomatid Virulence Factor." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.65 Å and deposited in 2010.

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

This PDB entry contains a complex of 2 biomacromolecules, namely OLIGOPEPTIDASE B and ANTIPAIN.

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 most likely forms heterodimers.
