Protein: Acetohydroxyacid synthase catalytic subunit from Thale cress (Arabidopsis thaliana), chloroplast [TaxId: 3702]

SQ P17597 86-280

Lineage:

1. Root: scop
2. Class: Alpha and beta proteins (a/b) [51349]
   Mainly parallel beta sheets (beta-alpha-beta units)
3. Fold: Thiamin diphosphate-binding fold (THDP-binding) [52517]
   3 layers: a/b/a; parallel beta-sheet of 6 strands, order 213465
4. Superfamily: Thiamin diphosphate-binding fold (THDP-binding) [52518]
   there are two different functional modules of this fold: pyridine-binding (Pyr) and pyrophosphate-binding (PP) modules
   two Pyr and two PP modules assemble together in a conserved heterotetrameric core that binds two THDP coenzyme molecules
   uperfamily
5. Family: Pyruvate oxidase and decarboxylase Pyr module [88724]
   the N-terminal, Pyr module is separated from the C-terminal, PP module by an alpha/beta domain of Rossmann-like topology
6. Protein: Acetohydroxyacid synthase catalytic subunit [88733]
7. Species: Thale cress (Arabidopsis thaliana), chloroplast [TaxId: 3702] [142204]
