Structure of the protein 1EFN, with focus on its tertiary structure. The term protein tertiary structure refers to a protein 's geometric shape. The tertiary structure will have a single polypeptide chain backbone with one or more protein secondary structures, the protein domains.

The protein tertiary structure is defined by its atomic coordinates.
