| Definition: | A motif of 4 consecutive residues with dihedral angles as follows: res i: phi -90 bounds -120 to -60, res i psi -10 bounds -50 to 30, res i+1: phi -90 bounds -120 to -60, res i+1: psi -10 bounds -50 to 30, res i+2: phi -75 bounds -100 to -50, res i+2: psi 140 bounds 110 to 170. The extra restriction of the length of the O to O distance is similar, that it be less than 5 Angstrom. In this case these two Oxygen atoms are the main chain carbonyl oxygen atoms of residues i-1 and i+2. |
