    International concern over the recent emergence of Candida auris infections reflects not only its comparative ease of transmission and substantial mortality but the increasing level of resistance observed to all three major classes of antifungal drugs. Diminution in virulence has been reported for a wide range of fungal pathogens when the FK506-binding protein FKBP12 binds to that immunosuppressant drug and the binary complex then inhibits the fungal calcineurin signaling pathway. Structure-based drug design efforts have described modifications of FK506 which modestly reduce virulence for a number of fungal pathogens while also lessening the side effect of suppressing the tissue immunity response in the patient. To aid in such studies, we report the crystal structure of Candida auris FKBP12. As physiological relevance has been proposed for transient homodimerization interactions of distantly related fungal FKBP12 proteins, we report the solution NMR characterization of the homodimerization interactions of the FKBP12 proteins from both Candida auris and Candida glabrata.
