Class b: All beta proteins [48724] (177 folds) |
Fold b.68: 6-bladed beta-propeller [50938] (11 superfamilies) consists of six 4-stranded beta-sheet motifs; meander |
Superfamily b.68.1: Sialidases [50939] (3 families) |
b.68.1.1: Sialidases (neuraminidases) [50940] (10 proteins) |
b.68.1.2: Endo-alpha-sialidase [117276] (2 proteins) possibly related by the other family by circular permutation; includes extra N-terminal domain [dN: alpha/beta ] and insert domain [dI: beta-barrel, similar to the Reductase/isomerase/elongation factor common domain (50412)] |
b.68.1.0: automated matches [191452] (1 protein) not a true family |
