| Three leucine residues and one glycine residue for the four heptad repeats in leucine zipper are highlighted by triangles. |
| The amino acids in the heptad repeats that constitute the predicted coiled-coil regions are underlined. |
| These core amino acids can be grouped into seven heptad repeats. |
| Add vowels to create words, then delete this heptad of words. |
| The inclusion of lactose was accommodated in both the final heptad towards the N-terminus, or more centrally in the penultimate heptad. |
| Coiled coils commonly contain a heptad of residues labeled A-G, repeated at least three or four times. |
