Cloning, expression, and characterization of an acetolactate synthase (ALS) gene from Anabaena azotica

Analysis of the ALS secondary structure of by DNAStar. Ribbon diagrams of the structure of an ALS monomer. (A) Displayed with the group color by Rasmol. The α-domain is shown in blue on top, the β-domain in green in the lower right, and the γ-domain in red in the lower left. (B) This diagram is in approximately the same orientation as (A) but shown in structure colour. The individual domains all have an α-β architecture comprising a central six-stranded parallel β-sheet with several helices surrounding the sheet on both sides.
