WebAug 1, 2011 · P -‘typical’ ATPase building blocks Since the discovery of the NKA ( Skou, 1957 ), our knowledge of the P-type ATPase family has grown considerably and it is now divided into five main classes (P1, P2, P3, P4 and P5) with subfamilies (P1A, P1B, etc.) ( Palmgren and Axelsen, 1998 ). 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.
