- Beta_bend_ribbon abstract "The beta bend ribbon, or beta-bend ribbon, is a structural feature in polypeptides and proteins. The shortest possible has six amino acid residues (numbered i to i+5) arranged as two overlapping hydrogen bonded beta turns in which the carbonyl group of residue i is hydrogen-bonded to the NH of residue i+3 while the carbonyl group of residue i+2 is hydrogen-bonded to the NH of residue i+5. In longer ribbons, this bonding is continued in peptides of 8, 10, etc., amino acid residues. A beta bend ribbon can be regarded as an aberrant 310 helix (3/10-helix) that has lost some of its hydrogen bonds. Two websites are available to facilitate finding and examining these features in proteins: Motivated Proteins; and PDBeMotif.The four main types of hydrogen-bonded beta turns are types I, I’, II and II’. Beta bend ribbons may be formed from any of these types but type I is the commonest in proteins, as it is for single beta turns. Beta bend ribbons made from type I or I’ turns are somewhat twisted, while beta bend ribbons made from type II or II’ beta turns are flat. Beta bend ribbons with mixtures of different beta turn types also occur.Type I beta-bend ribbons regularly occur in leucine-rich repeats, in the environments sometimes occupied by helices. A protein with a stack of these features is the extracellular ligand-binding domain of the Nogo receptor. Another beta bend ribbon occurs in the GTPase-activating protein for Rho in the active, but not the inactive, form of the enzyme. The beta bend ribbon, which incorporates the catalytic arginine, allows its side-chain guanidino group to approach the active site and enhance enzyme activity.Polypeptides consisting of repeats of the dipeptide (α-amino-γ-lactam plus a conventional amino acid) have been shown to adopt a beta bend ribbon conformation.".
