Class a: All alpha proteins [46456] (284 folds) |
Fold a.25: Ferritin-like [47239] (6 superfamilies) core: 4 helices; bundle, closed, left-handed twist; 1 crossover connection |
Superfamily a.25.3: EsxAB dimer-like [140453] (1 family) (hetero)dimer of alpha-hairpin subunits similar to that of the half-ferritin family; no bound metals |
a.25.3.1: ESAT-6 like [140454] (3 proteins) Pfam PF06013; the conserwed WxG motif makes the turn at the alpha-hairpin tip |
