<P> ATP synthase consists of two main subunits, F and F, which has a rotational motor mechanism allowing for ATP production . Because of its rotating subunit ATP Synthase is a molecular machine . </P> <P> The F fraction derives its name from the term "Fraction 1" and F (written as a subscript letter "o", not "zero") derives its name from being the binding fraction for oligomycin, a type of naturally - derived antibiotic that is able to inhibit the F unit of ATP synthase . These functional regions consist of different protein subunits--refer to tables . </P> <P> Located within the thylakoid membrane and the inner mitochondrial membrane, ATP synthase consists of two regions F and F. F causes rotation of F and is made of c - ring and subunits a, b, d, F6. F is made of α, β, γ, δ (\ displaystyle \ alpha, \ beta, \ gamma, \ delta) subunits . F has a water - soluble part that can hydrolyze ATP . F on the other hand has mainly hydrophobic regions . F F creates a pathway for protons movement across the membrane . </P> <P> The F portion of ATP synthase is hydrophilic and responsible for hydrolyzing ATP . Subunits α (\ displaystyle \ alpha) and β (\ displaystyle \ beta) make a hexamer with 6 binding sites . Three of them are catalytically inactive and they bind ADP . </P>
