ID: SO_0001135
Class
Left handed type II: A motif of four consecutive residues that may contain one H-bond, which, if present, is between the main-chain CO of the first residue and the main-chain NH of the fourth. It is characterized by the dihedral angles: Residue(i+1): -140 degrees > phi > -20 degrees, +80 degrees > psi > +180 degrees. Residue(i+2): +20 degrees > phi > +140 degrees, -40 degrees > psi > +90 degrees.
