Fold: Folate-binding domain [103024]
duplication: consists of two beta(2)-alpha-beta(3)-alpha subdomains swapped with the first strands
Superfamily: Folate-binding domain [103025]
some topological similarity to Formylmethanofuran:tetrahydromethanopterin formyltransferase uperfamily
Family: TrmE formyl-THF-binding domain [117997]
dimeric biological unit; one subunit domain corresponds to one "unswapped" subdomain of the other family
