The two remaining T's have one residue segments, and these could possibly be a 3-turn with that one residue being the central residue of the turn, but it could also be a residue of a 4-turn with some of the other residues also being part of a helix which has priority over a turn. This seems to be the case for the turns that are identified as A:86_A:86 and A:110_A:110. As described above the summary often identifies β-turns (4-turns) with the two interior residues, but in the case of A:86_A:86 (Display with green link below) residue A:85 is part of an α-helix so it is included as part of that helix. In the case of A:110_A:110 (Display with green link below) A:110 and A:113 are hydrogen bonded which qualifies it for a 4-turn, and the phi and psi angles of A:111 and A:112 qualify it for a class I β-turn. | The two remaining T's have one residue segments, and these could possibly be a 3-turn with that one residue being the central residue of the turn, but it could also be a residue of a 4-turn with some of the other residues also being part of a helix which has priority over a turn.

There are two β-turns that are not detected by DSSP, and they are both class IVB. They are located at residues 5-8 and 88-91. | There are two β-turns that are not detected by DSSP, and they are both class IVB which do not have a hbond. They are located at residues 5-8 and 88-91. | ||
