SCOP 1.75: Superfamily b.45.1: FMN-binding split barrel

Lineage for Superfamily b.45.1: FMN-binding split barrel

1. Root: SCOP 1.75

2. Class b: All beta proteins [48724] (174 folds)

3. Fold b.45: Split barrel-like [50474] (3 superfamilies)
   barrel; n=6, S=10; greek-key

4. Superfamily b.45.1: FMN-binding split barrel [50475] (4 families)
   related to the ferredoxin reductase-like FAD-binding domain

Families:

1. b.45.1.1: PNP-oxidase like [50476] (16 proteins)

2. b.45.1.2: NADH:FMN oxidoreductase-like [50482] (5 proteins)
   different dimerization mode than in the PNP-oxidase like family

3. b.45.1.3: UbiD middle domain-like [141368] (1 protein)
   N terminal part of Pfam PF01977; overall structural similarity to one subunit of the NADH:FMN oxidoreductase-like family ((50482)); not known to bind a flavin cofactor; also includes the N-terminal alpha+beta subdomain (~110 residues)

4. b.45.1.4: MTH863-like [159164] (3 proteins)
   Pfam PF04289; DUF447; a new dimerisation mode involving (included) all-alpha subdomain of the spectrin-like fold ((46965))
