Protein Structural Conformational Change - Ribbon Diagram Visualization #1404144 (License: Personal Use)

This composite image displays four views (A-D) of a protein’s tertiary structure using ribbon diagrams: green and orange represent α-helices, gray indicates β-sheets, and red highlights loop regions. Panel B transitions via a 60° rotation to panel C, revealing domain mobility critical for function. Labels (I, II, III, N, C) denote structural domains and termini.

Used in academic or research web pages on protein dynamics, enzymology, or structural bioinformatics; serves users seeking visual explanations of conformational changes in macromolecules.
