Lineage for Family a.100.1.11: HMD dimerization domain-like

1. Root: SCOP 1.73

2. Class a: All alpha proteins [46456] (258 folds)

3. Fold a.100: 6-phosphogluconate dehydrogenase C-terminal domain-like [48178] (1 superfamily) multihelical; common core is formed around two long antiparallel helices related by (pseudo) twofold symmetry

4. Superfamily a.100.1: 6-phosphogluconate dehydrogenase C-terminal domain-like [48179] (12 families) N-terminal domain is Rossmann-fold with a family-specific C-terminal extension

5. Family a.100.1.11: HMD dimerization domain-like [140777] (1 protein) dimer similar to those of the GDP-mannose 6-dehydrogenase and class I KARI domains
