The immunosuppressant tacrolimus (FK506) inhibits C. glabrata Cdr1 efflux pump function by stabilizing the inward-facing conformation
CryoEM structure of CgCdr1 in complex with FK506 revealed that FK506 binds within the drug-binding site of CgCdr1, occupying the space occupied by Itraconazole, demonstrating that FK506’s inhibition extends beyond competitive binding, involving allosteric modulation of the ATPase cycle.
