Superfamily: Barwin-like endoglucanases

Lineage:

1. Root: scop
2. Class: All beta proteins
3. Fold: Double psi beta-barrel
   barrel, closed; n=6, S=10; complex topology with crossover (psi) loops
4. Superfamily: Barwin-like endoglucanases

Families:

1. Endoglucanase V (Eng V) (1)
2. Pollen allergen PHL P 1 N-terminal domain (1)
   conserved Eng V active site residues and disulfides; better structural similarity to the ADC-like superfamily
3. Barwin (1)
