The image on the left shows a comparison of the medium-resolution structure of P-glycoprotein (green) obtained in the lab with the high resolution structure of Sav1866 (yellow) produced by Kaspar Locher's lab in Zurich. On the right, the front half of the 3D structures have been stripped away to reveal the way the two halves of the transporter wrap around each other - something like Rodin's 'The Kiss' (centre).
