Protein: TonB from Escherichia coli [TaxId: 562]

SQ P02929 150-239

Lineage:

1. Root: scop
2. Class: Alpha and beta proteins (a+b) [53931]
   Mainly antiparallel beta sheets (segregated alpha and beta regions)
3. Fold: TolA/TonB C-terminal domain [74652]
   beta(2)-alpha-beta; 2 layers, alpha/beta; left-handed beta-alpha-beta unit in non-swapped monomer
4. Superfamily: TolA/TonB C-terminal domain [74653]
   uperfamily
5. Family: TonB [64326]
   isolated domain can form different segment-swapped dimers depending on the fragment length
6. Protein: TonB [64327]
7. Species: Escherichia coli [TaxId: 562] [64328]
   SQ P02929 150-239
