Class b: All beta proteins [48724] (174 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 |
b.82.1: RmlC-like cupins [51182] (25 families) |
b.82.2: Clavaminate synthase-like [51197] (14 families) Iron and ketoglutarate-dependent enzymes; elaborated version of this common fold |
b.82.3: cAMP-binding domain-like [51206] (3 families) |
b.82.4: Regulatory protein AraC [51215] (1 family) |
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.82.6: Thiamin pyrophosphokinase, substrate-binding domain [63862] (1 family) |
b.82.7: Calcium ATPase, transduction domain A [81653] (1 family) a distorted variant of double-helix |
