SCOP 1.75: Superfamily b.82.5: TRAP-like

Lineage for Superfamily b.82.5: TRAP-like

1. Root: SCOP 1.75

2. Class b: All beta proteins [48724] (174 folds)

3. Fold b.82: Double-stranded beta-helix [51181] (7 superfamilies)
   one turn of helix is made by two pairs of antiparallel strands linked with short turns
   has appearance of a sandwich of distinct architecture and jelly-roll topology

4. Superfamily b.82.5: TRAP-like [51219] (2 families)
   shorter variant of double-helix; assembles in large ring-like structures containing from 9 to 11 domains

Families:

1. b.82.5.1: Trp RNA-binding attenuation protein (TRAP) [51220] (1 protein)
   oligomeric ring consists of 11 single-domain subunits

2. b.82.5.2: PA3696/SPS0176-like [101995] (2 proteins)
   duplication: there are three structural repeats per subunit; nine domains per ring-like trimer
