This entry describes the actuator (A) domain found in P-type ATPases (also known as E1-E2 ATPases). The A domain serves as a built-in protein phosphatase that functions to dephosphorylate the phosphorylated P domain. The A domain is the smallest of the three cytoplasmic domains. It consists of a distorted jellyroll structure and two short helices [1-2].
