310heliksiäs

310heliksiäs is a term that refers to a specific type of helical structure found in certain protein motifs. The designation "310" indicates a particular pitch and radius that define the helix's conformation. These helices are often shorter and more tightly coiled than the more common alpha (α) helix. The 310 helix is characterized by its hydrogen bonding pattern, where the i+3 side chain is involved in stabilizing the helix. This contrasts with the i+4 hydrogen bond in alpha helices. While less prevalent than alpha helices in globular proteins, 310 helices can play significant roles in protein structure and function, particularly in areas where a tighter turn or specific spatial arrangement is required. They are sometimes found at the termini of alpha helices or in loop regions. The precise formation and stability of a 310 helix are influenced by factors such as amino acid sequence and the surrounding environment.
