Class b: All beta proteins [48724] (174 folds) |
Fold b.33: ISP domain [50021] (1 superfamily) consists of two all-beta subdomains: conserved small domain has a rubredoxin-like fold; larger domain consists of 6 beta-stands packed in either sandwich of two 3-stranded sheets or closed barrel (n=6; S=8) |
Superfamily b.33.1: ISP domain [50022] (4 families) |
b.33.1.1: Rieske iron-sulfur protein (ISP) [50023] (9 proteins) |
b.33.1.2: Ring hydroxylating alpha subunit ISP domain [50033] (6 proteins) |
b.33.1.3: NirD-like [158991] (1 protein) retains the common fold but lacks the Fe-S cluster automatically mapped to Pfam PF13806 |
b.33.1.0: automated matches [191455] (1 protein) not a true family |
