Class d: Alpha and beta proteins (a+b) [53931] (396 folds) |
Fold d.250: Folate-binding domain [103024] (1 superfamily) duplication: consists of two beta(2)-alpha-beta(3)-alpha subdomains swapped with the first strands |
Superfamily d.250.1: Folate-binding domain [103025] (2 families) some topological similarity to Formylmethanofuran:tetrahydromethanopterin formyltransferase |
d.250.1.1: Aminomethyltransferase folate-binding domain [103026] (4 proteins) |
d.250.1.2: TrmE formyl-THF-binding domain [117997] (1 protein) dimeric biological unit; one subunit domain corresponds to one "unswapped" subdomain of the other family automatically mapped to Pfam PF10396 |
