Figure 3. Main features of a hypothetical model of kNBC1 transport.

Figure 3

A, blockage of a putative bicarbonate transport site by Asp986 and Asp988 when kNBC1-Ser982 is phosphorylated and kNBC1 operates in the 2:1 mode. B, interaction of CAII with kNBC1-Ct enhances the flux through the transporter in the 3:1 mode.
