Description | P-ATPases (also known as E1-E2 ATPases) ([intenz:3.6.3.-]) are found in bacteria and in a number of eukaryotic plasma membranes and organelles []. P-ATPases function to transport a variety of different compounds, including ions and phospholipids, across a membrane using ATP hydrolysis for energy. There are many different classes of P-ATPases, which transport specific types of ion: H+, Na +, K +, Mg 2+, Ca 2+, Ag +and Ag 2+, Zn 2+, Co 2+, Pb 2+, Ni 2+, Cd 2+, Cu +and Cu 2+. P-ATPases can be composed of one or two polypeptides, and can usually assume two main conformations called E1 and E2. This superfamily represents the cytoplasmic domain N found in P-type ATPases. The cytoplasmic loops of the P-type ATPases form three separate modules, commonly named the A, P and N-domains [ , . The N-domain comprises the nucleotide binding site [ ]. This domain forms a seven-stranded antiparallel β-sheet with two additional β-strands forming a hairpin and five α-helices []. |
