TRIMCyp cyclophilin domain from Macaca mulatta: HIV-2 CA cyclophilin-binding loop complex

The structure was published by Caines, M.E., Bichel, K., Price, A.J., et al., Willett, B.J., Freund, S.M., and James, L.C., in 2012 in a paper entitled "Diverse HIV viruses are targeted by a conformationally dynamic antiviral." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.702 Å and deposited in 2012.

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

This PDB entry contains a complex of 2 biomacromolecules, namely TRIMCyp and capsid protein.
