Fig. 1. Subunit composition and architecture of the monomeric yeast ATP synthase.

The subunits are in a variety of colors to allow identification. The chain number or letter used in the pdb is shown in the brackets. There are 3 α- (red) and 3 β-subunits (blue) that with the γ-, δ-, and ε-subunits form F₁. The rotor is comprised of the γ-, δ- and ε-subunits of F₁. The core of F_o is comprised of the a-subunit and the c₁₀-ring. The subunit of the stator are as shown.
