  • PubMed Abstract: 

    Cyclophilin D (CypD) is a key mitochondrial target for amyloid-β-induced mitochondrial and synaptic dysfunction and is considered a potential drug target for Alzheimer's disease. The high-resolution crystal structures of primitive orthorhombic (CypD-o) and primitive tetragonal (CypD-t) forms have been determined to 1.45 and 0.85 Å resolution, respectively, and are nearly identical structurally. Although an isomorphous structure of CypD-t has previously been reported, the structure reported here was determined at atomic resolution, while CypD-o represents a new crystal form for this protein. In addition, each crystal form contains a PEG 400 molecule bound to the same region along with a second PEG 400 site in CypD-t which occupies the cyclosporine A inhibitor binding site of CypD. Highly precise structural information for CypD should be extremely useful for discerning the detailed interaction of small molecules, particularly drugs and/or inhibitors, bound to CypD. The 0.85 Å resolution structure of CypD-t is the highest to date for any CypD structure.
