Lineage for Protein: 17-beta-hydroxysteroid dehydrogenase type XI

1. Root: SCOPe 2.08

2. Class c: Alpha and beta proteins (a/b) [51349] (148 folds)

3. Fold c.2: NAD(P)-binding Rossmann-fold domains [51734] (1 superfamily) core: 3 layers, a/b/a; parallel beta-sheet of 6 strands, order 321456 The nucleotide-binding modes of this and the next two folds/superfamilies are similar

4. Superfamily c.2.1: NAD(P)-binding Rossmann-fold domains [51735] (13 families)

5. Family c.2.1.2: Tyrosine-dependent oxidoreductases [51751] (73 proteins) also known as short-chain dehydrogenases and SDR family parallel beta-sheet is extended by 7th strand, order 3214567; left-handed crossover connection between strands 6 and 7 has additional subdomain(s) that are not in the common domain

6. Protein 17-beta-hydroxysteroid dehydrogenase type XI [117426] (1 species)
