WebMar 4, 2024 · The P-type ATPases, which constitute a large superfamily of membrane pumps that catalyze the transmembrane transport of diverse substrates, all contain a common structural core composed of a transmembrane domain (TMD), an actuator (A) domain, a phosphorylation (P) domain, and a nucleotide-binding (N) domain ( 1 ). P-type ATPases have a single catalytic subunit of 70 - 140 kDa. The catalytic subunit hydrolyzes ATP, contains the aspartyl phosphorylation site and binding sites for the transported ligand(s) and catalyzes ion transport. Various subfamilies of P-type ATPases also need additional subunits for proper function. … See more The P-type ATPases, also known as E1-E2 ATPases, are a large group of evolutionarily related ion and lipid pumps that are found in bacteria, archaea, and eukaryotes.
