WebP-type ATPases are a large family of membrane proteins that perform active ion transport across biological membranes. In these proteins, the energy-providing ATP hydrolysis is coupled to ion transport of one or two ion species across the respective membrane. The pump function of the investigated pumps is described by a so-called Post-Albers cycle. WebP-type ATPases undergo phosphorylation as they transport cations such as Na+, K+, and Ca2+ F-type ATPase proton-transporting complexes located in mitochondria and bacteial membranes. Proteins operate in reverse to synthesize ATP V-type ATPase resemble the F-type ATPases and occur in plant vacuoles and acidic vesicles such as animal lysosomes
