proton-transporting ATP synthase complex, catalytic core F(1)
proton-transporting atp synthase complex, catalytic core f(1)
"The sector of a hydrogen-transporting ATP synthase complex in which the catalytic activity resides; it comprises the catalytic core and central stalk, and is peripherally associated with a membrane, such as the plasma membrane or the mitochondrial inner membrane, when the entire ATP synthase is assembled."
