Query used to return relevant dipeptides from the CSD. (a) Key peptide query and returned data parameters. (b) An improper torsion angle used to constrain the search to L-amino-acid dipeptide fragments. To ensure that we only extract peptidic fragments from L-amino-acid systems, we constrain the results so that the improper torsion angle C7–C8–C5–N3 is in the range 0.0–180°.
