Lineage for Family a.223.1.2: Porin chaperone SurA, peptide-binding domain

1. Root: SCOPe 2.08

2. Class a: All alpha proteins [46456] (290 folds)

3. Fold a.223: Triger factor/SurA peptide-binding domain-like [109997] (1 superfamily) multihelical; irregular array of long and short helices

4. Superfamily a.223.1: Triger factor/SurA peptide-binding domain-like [109998] (3 families) there are sequence and functional similarities between the families, but their structural similarity is obscured by conformational flexibility (in the TF family)

5. Family a.223.1.2: Porin chaperone SurA, peptide-binding domain [81828] (1 protein)
