PDB entry 2q5a (supersedes 2iti)

human Pin1 bound to L-PEPTIDE

The structure was published by Zhang, Y., Daum, S., Wildemann, D., et al., Lu, K.P., Fischer, G., and Noel, J.P., in 2007 in a paper entitled "Structural basis for high-affinity peptide inhibition of human Pin1." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.5 Å and deposited in 2007.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 and Five residue peptide.

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.
