simulated annealing omit maps. (A) The electron density of the
AMPPNP (blue, contoured at 4σ). (B) The electron densities of
the ATP (blue, 5.5σ) and the Mg^2+ (brown, 4σ). The continuity
of the electron densities of the Mg^2+, Asp36, and Asp137 is
shown by omitting these three molecules (yellow, 3σ). (C) The
electron densities of the L-lysine (blue, 3.5σ).
(D)
Ribbon model of the TilS dimer. Two subunits (molecules A and B
of TilS/ATP/Mg/Lys) are colored pink and cyan, respectively. The
ATP and L-lysine molecules are shown by stick models.
(E) A
stereoview of the TilS monomer (molecule B of TilS/ATP/Mg/Lys).
The N-terminal domain (NTD), the TilS-specific subdomain (TSD),
the linker, and the C-terminal domain (CTD1) are colored pink,
yellow, green, and cyan, respectively. The graphic figures in
this paper were prepared with CueMol
