'''Structure of the multidrug ABC transporter Sav1866 from S. aureus in complex with AMP-PNP'''<br />


==Overview==
==Structure of the multidrug ABC transporter Sav1866 from S. aureus in complex with AMP-PNP==
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.

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.
