Lineage for Protein: Class I ketol-acid reductoisomerase (KARI)
- Root: SCOP 1.71
Class c: Alpha and beta proteins (a/b) [51349] (134 folds) 
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 similarSuperfamily c.2.1: NAD(P)-binding Rossmann-fold domains [51735] (12 families) 
Family c.2.1.6: 6-phosphogluconate dehydrogenase-like, N-terminal domain [51868] (15 proteins)
the beta-sheet is extended to 8 strands, order 32145678; strands 7 & 8 are antiparallel to the rest
C-terminal domains also show some similarity
