Adenosine triphosphatase

Definition

noun

An enzyme that catalyzes the hydrolysis or decomposition of adenosine triphosphate (or ATP) into adenosine diphosphate (or ADP) and a free phosphate ion, thereby releasing energy for in another biochemical reaction.


Supplement

Examples of ATPases are transmembrane ATPases that move solutes across the membrane, especially against their concentration gradient. and V-ATPases that are primarily found in eukaryotic vacuoles, catalysing ATP hydrolysis to transport solutes and lower pH in organelles.
