Bicarbonate ABC transporter CmpA

From the Smith lab: Shown in the foreground is the structure of a solute binding domain from a bicarbonate ABC transporter from Synechocystis 6803 called CmpA. The red and white molecule in the central 'mouth' of the protein is the bound bicarbonate moiety. In the background are fluorescence microscopy images of Synechocystis. This protein has remarkable selectivity for bicarbonate over nitrate and carbonic acid. Koropatkin, N. M., Koppenaal, D. W., Pakrasi, H. B., Smith, T. J.
