Illustration of a Protein Structure

This illustration presents a three-dimensional representation of a protein molecule, rendered using a ribbon diagram technique. The protein is depicted with a rainbow color scheme, transitioning from yellow and green on one side to blue, purple, and red on the other, which often signifies different domains or the polypeptide chain's progression. Clear secondary structural elements are visible, including extended beta-sheets and coiled alpha-helices. Nestled within a binding pocket of the protein is a smaller molecule, possibly a ligand or an ion, shown in a more detailed ball-and-stick model with a central grey sphere and surrounding green and red atoms. The black background ensures the intricate protein structure is the sole focus.
