Co-crystal Structure

Interaction directly demonstrated at the atomic level by X-ray crystallography. Also used for NMR or Electron Microscopy (EM) structures. If there is no obvious bait-hit directionality to the interaction involving 3 or more proteins, then the co-crystallized proteins should be listed as a complex.

Crystal structure of calcineurin-cyclophilin-cyclosporin shows common but distinct recognition of immunophilin-drug complexes.

Calcineurin, a Ca2+/calmodulin-dependent protein phosphatase, is the common target for two immunophilin-immunosuppressant complexes, cyclophilin A-cyclosporin A (CyPA-CsA) and FKBP-FK506. How the two structurally distinct immunophilin-drug complexes bind the same target has remained unknown. We report the crystal structure of calcineurin (CN) in complex with CyPA-CsA at 2.8-A resolution. The CyPA-CsA complex binds to a composite surface formed by the catalytic ... [more]
