This protein structure template demonstrates hierarchical organization from primary amino acid sequence through secondary structures like α-helices and β-sheets, tertiary three-dimensional folding stabilized by various bonds, quaternary multi-subunit assembly, to supramolecular complexes. It systematically categorizes protein functions including signal transduction with receptors and kinases, structural support from collagen and cytoskeletal proteins, motor proteins generating movement, catalytic enzymes accelerating reactions, and transport proteins carrying molecules. Invaluable for biochemistry courses, molecular biology education, and drug design.
