Chaperonin ATPase (EC 3.6.4.9, chaperonin) is an enzyme with systematic name ATP phosphohydrolase (polypeptide-unfolding).[1][2][3][4] This enzyme catalyses the following chemical reaction
- ATP + H2O [math]\displaystyle{ \rightleftharpoons }[/math] ADP + phosphate
These enzymes are a subclass of molecular chaperones.
