Steroid-transporting ATPase (EC 3.6.3.45, pleiotropic-drug-resistance protein, PDR protein) is an enzyme with systematic name ATP phosphohydrolase (steroid-exporting).[1][2][3] This enzyme catalyses the following chemical reaction

ATP + H2O + steroidin ADP + phosphate + steroidout

This enzyme has two similar ATP-binding domains.
