Class b: All beta proteins [48724] (178 folds) |
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 |
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 |
b.82.5.1: Trp RNA-binding attenuation protein (TRAP) [51220] (2 proteins) oligomeric ring consists of 11 single-domain subunits automatically mapped to Pfam PF02081 |
b.82.5.2: PA3696/SPS0176-like [101995] (2 proteins) duplication: there are three structural repeats per subunit; nine domains per ring-like trimer automatically mapped to Pfam PF01987 |
