Function
Y1866_STAAM May be involved in multidrug export. Transmembrane domains (TMD) form a pore in the cell membrane and the ATP-binding domain (NBD) is responsible for energy generation.

Publication Abstract from PubMed
Staphylococcus aureus Sav1866 is a bacterial homolog of the human ABC transporter Mdr1 that causes multidrug resistance in cancer cells. We report the crystal structure of Sav1866 in complex with adenosine-5'-(beta,gamma-imido)triphosphate (AMP-PNP) at 3.4A resolution and compare it with the previously determined structure of Sav1866 with bound ADP. Besides differences in the ATP-binding sites, no significant conformational changes were observed. The results confirm that the ATP-bound state of multidrug ABC transporters is coupled to an outward-facing conformation of the transmembrane domains.
