ATPases (EC 3.6.1.3, Adenosine 5'-TriPhosphatase, adenylpyrophosphatase, ATP monophosphatase, triphosphatase, SV40 T-antigen, ATP hydrolase, complex V (mitochondrial electron transport), (Ca 2+ + Mg 2+)-ATPase, HCO 3 −-ATPase, adenosine triphosphatase) are a class of enzymes that catalyze the decomposition of ATP into ADP and a free phosphate ...

2019年2月26日 · Adenosine triphosphate (ATP) is a key molecule which upon hydrolysis provides energy to facilitate a variety of cellular processes that are essential for life. The cell utilizes the energy of...

2020年4月1日 · The main difference between ATPase and ATP synthase is that ATPase is the enzyme, which breaks down ATP into ADP and free phosphate group. In contrast, ATP synthase is the enzyme, which synthesizes ATP by combining ADP and a free phosphate group.

Adenosine triphosphate-hydrolyzing enzymes, or ATPases, play a critical role in a diverse array of cellular functions. These dynamic proteins can generate energy for mechanical work, such as protein trafficking and degradation, solute transport, and cellular movements.

ATP synthase, also called F 1 F o ATPase, is a rotary motor enzyme. This enzyme is found in the inner membrane of mitochondria, the analogous thylakoid membranes of chloroplasts, and the cell membrane of bacteria.

ATPases are a group of enzymes that catalyze the hydrolysis of a phosphate bond in adenosine triphosphate (ATP) to form adenosine diphosphate (ADP). They harness the energy released from the breakdown of the phosphate bond and utilize it to perform other cellular reactions.

ATPases are a group of enzymes that couple ATP synthesis or hydrolysis to the transport of ions across membranes. A gradient of protons is the driving force for ATP synthesis, whereas the ATP hydrolysis releases the energy necessary for ion pumping.

ATPase is a conventional name for a large group of membrane proteins, which couple ATP hydrolysis with a vectorial translocation of cations across a lipid bilayer. In general, these enzymes have two moieties.

ATP synthase is the ubiquitous enzyme, which is observed in various energy-transducing membranes such as thylakoid membranes in chloroplasts and cyanobacteria, inner membranes of mitochondria, and plasma membranes of prokaryotic bacteria.

The term ATPase applies to the activity of any enzyme’s ability to decompose ATP, including metabolic enzymes involved in anabolic processes that need energy, as well as enzymes promoting transport across membrane.
