Fig. 1. The overall fold of AtAHAS. (A) The tetrameric
structure with each monomer colored separately. (B) A single
subunit. The individual domains (86-280), (281-451), and (463-639) are colored
gold, red, and blue, respectively. The C-terminal tail (646-668)
is colored green. ThDP, Mg2+, FAD, and IQ are shown as
ball-and-stick models and are colored red, dark blue, cyan, and
yellow, respectively.
