The end of the protein that harvests sunlight in photosynthesis may have a compact, helix-like structure - but only when phosphate (a yellow atom joined to four red ones) is attached. This change in structure regulates the conversion of energy from sunlight, which supports all life on earth. Slide the movie controller from side to side to gain a full impression of depth.
This structure can also be viewed interactively.
