Secondary structure refers to a protein's local three-dimensional structure, for example alpha helices and beta sheets are secondary structure. The structure on the right of a human transferrin n-lobe mutant (PDB code 1dtg) is shown in cartoon backbone representation to highlight its secondary structure, with alpha-helices in magenta and beta-sheets in yellow.
