title: [Plant P-type ATPases].
abstract: P-type ATPases are a superfamily of membrane proteins involved in many physiological processes that are fundamental for all living organisms. Using ATP, they can transport a variety of ions and other substances across all types of cell membranes against a concentration electrochemical gradient. P-type ATPases form a phosphorylated intermediate and are sensitive to vanadate. Based on evolutionary relations and sequence homology, P-type ATPases are divided into five major families. All P-type ATPases share a simple structure and mechanism, but also possess domains characteristic for each family, which are crucial for substrate specificity. These proteins usually have a single subunit with eight to twelve transmembrane segments, a large central cytoplasmic domain with the conservative ATP binding site along with N and C termini exposed to the cytoplasm. Because of variety of proteins that belong to P-type ATPase superfamily, in this review the comparison of functional and structure properties of plant cells P-type ATPases is presented, as well as their important role in adaptation to environmental stress.
