UbiD middle domain-like [141368] (1) N terminal part of Pfam 01977; 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)
MTH863-like [159164] (3) Pfam 04289; DUF447; a new dimerisation mode involving (included) all-alpha subdomain of the spectrin-like fold (scop_cf 46965)
