SYSTEMATIC NAME
IUBMB Comments
ATP phosphohydrolase (H+-transporting)
A multisubunit non-phosphorylated ATPase that is involved in the transport of ions. Large enzymes of mitochondria, chloroplasts and bacteria with a membrane sector (Fo, Vo, Ao) and a cytoplasmic-compartment sector (F1, V1, A1). The F-type enzymes of the inner mitochondrial and thylakoid membranes act as ATP synthases. All of the enzymes included here operate in a rotational mode, where the extramembrane sector (containing 3 alpha- and 3 beta-subunits) is connected via the delta-subunit to the membrane sector by several smaller subunits. Within this complex, the gamma- and epsilon-subunits, as well as the 9--12 c subunits rotate by consecutive 120_degree_ angles and perform parts of ATP synthesis. This movement is driven by the H+ electrochemical potential gradient. The V-type (in vacuoles and clathrin-coated vesicles) and A-type (archaeal) enzymes have a similar structure but, under physiological conditions, they pump H+ rather than synthesize ATP.

the enzyme couples the hydrolysis of ATP to the translocation of H+ across the membrane with generation of an electrochemical potential for H+. In fermentative bacteria the ATPase functions physiologically as an ATP-utilizing, electrogenic H+ pump, the electrochemical potential of H+ generated is ultilized as a driving force for transport and mobility, in facultative anaerobes the ATPase can function physiologically in either direction, depending upon the presence or the absence of oxygen

catalytic mechanism of F1-ATPase by structure-function relationship analysis, overview. During hydrolysis of ATP, the rotor turns counterclockwise as viewed from the membrane domain of the intact enzyme in 120 degree steps. Because the rotor is asymmetric, at any moment the three catalytic sites are at different points in the catalytic cycle. One site is devoid of nucleotide and represents a state that has released the products of ATP hydrolysis. A second site has bound the substrate, magnesium. ATP, in a precatalytic state, and in the third site, the substrate is about to undergo hydrolysis
