Channel-conductance-controlling ATPase

In enzymology, a channel-conductance-controlling ATPase is an enzyme that catalyzes the chemical reaction


 * ATP + H2O $$\rightleftharpoons$$ ADP + phosphate

Thus, the two substrates of this enzyme are ATP and H2O, whereas its two products are ADP and phosphate.

This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides to catalyse transmembrane movement of substances. The systematic name of this enzyme class is ATP phosphohydrolase (channel-conductance-controlling).

Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and.
