Atp synthase

Large lollipop-shaped rotary membrane enzyme complex spanning a lipid membrane. A prominent rounded catalytic head projects from one side of the membrane, appearing as a spherical, ring-like, or hexameric knob. The head is connected by a narrow central stalk to a wider membrane-embedded base composed of a cylindrical rotor-stator assembly with multiple transmembrane segments and a central channel or rotor ring within the bilayer. A side stator arm may be visible, and the subunits are clearly segmented, giving the overall structure a symmetrical mushroom-like or turbine-like silhouette that reads as a rotary molecular machine. Protein tones are typically blue, gray, teal, purple, or green scientific illustration colors.
