SCOPe 2.05: Fold b.81: Single-stranded left-handed beta-helix

Lineage for Fold b.81: Single-stranded left-handed beta-helix

1. Root: SCOPe 2.05

2. Class b: All beta proteins [48724] (176 folds)

3. Fold b.81: Single-stranded left-handed beta-helix [51160] (4 superfamilies)
   superhelix turns are made of parallel beta-strands and (short) turns

Superfamilies:

1. b.81.1: Trimeric LpxA-like enzymes [51161] (9 families)
   superhelical turns are made of three short strands; duplication: the sequence hexapeptide repeats correspond to individual strands

2. b.81.2: An insect antifreeze protein [51177] (1 family)
   superhelical turns are made of three short strands

3. b.81.3: Adhesin YadA, collagen-binding domain [101967] (1 family)
   superhelical turns are made of two short strands

4. b.81.4: Guanosine diphospho-D-mannose pyrophosphorylase/mannose-6-phosphate isomerase linker domain [159283] (1 family)
   probable rudiment form of the LpxA-like hexapeptide domain
