Figure 1.
Figure 1: Overall structure of the plasma membrane H^+-ATPase. The structure represents an active form of the proton pump, without its auto-inhibitory C terminus, in complex with Mg-AMPPCP. Ten transmembrane helices, orange, green and brown, as indicated; nucleotide-binding domain (N), red; the phosphorylation domain (P), blue; and the actuator domain (A), yellow. Mg-AMPPCP is found at the interface between the N and P domains and is shown as a ball-and-stick reprentation. Key residues mentioned in the text are shown as sticks. The grey box depicts the approximate location of the plasma membrane.
