Physiology

Hydrogen potassium atpase

A specialized transmembrane H+/K+ ATPase exchange pump shown as a robust, asymmetrical multi-pass membrane protein embedded in the membrane. The protein has a broad membrane-spanning transport core with a central channel-like region, two directional ion openings or labeled ion-binding pockets, and a distinct cytoplasmic ATP-binding/catalytic ATPase domain that appears bulbous but smaller than the full transport core. The overall silhouette should clearly read as an active ion pump rather than a simple channel. Use teal, blue-green, and blue tones with gold accent details.
