Structural Classification of Proteins

Fold: Periplasmic binding protein-like II

: consists of two similar intertwined domain with 3 layers (a/b/a) each: duplication
mixed beta-sheet of 5 strands, order 21354; strand 5 is antiparallel to the rest

Lineage:

Root: scop
Class: Alpha and beta proteins (a/b) [51349]
Mainly parallel beta sheets (beta-alpha-beta units)
Fold: Periplasmic binding protein-like II [53849]
consists of two similar intertwined domain with 3 layers (a/b/a) each: duplication
mixed beta-sheet of 5 strands, order 21354; strand 5 is antiparallel to the rest

Superfamilies:

Periplasmic binding protein-like II [53850] (3)
Similar in architecture to the superfamily I but partly differs in topology
