Lineage for Family b.45.1.3: UbiD middle domain-like

1. Root: SCOP 1.73

2. Class b: All beta proteins [48724] (165 folds)

3. Fold b.45: Split barrel-like [50474] (2 superfamilies) barrel; n=6, S=10; greek-key

4. Superfamily b.45.1: FMN-binding split barrel [50475] (3 families) related to the ferredoxin reductase-like FAD-binding domain

5. Family 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 (scop_fa 50482); not known to bind a flavin cofactor; also includes the N-terminal alpha+beta subdomain (~110 residues)
