Coiled coil

Index Coiled coil

A coiled coil is a structural motif in proteins in which 2–7 alpha-helices are coiled together like the strands of a rope (dimers and trimers are the most common types). [1]

Alpha helix

The alpha helix (α-helix) is a common motif in the secondary structure of proteins and is a righthand-spiral conformation (i.e. helix) in which every backbone N−H group donates a hydrogen bond to the backbone C.
