Figure 1 Thermus thermophilus GluRS crystal structures. (A)
Ribbon representation of the ERS/ATP/Glu structure. Five
domains, the Rossmann fold (1), connective peptide (or
acceptor-binding) (2), stem-contact fold (3) and two
anticodon-binding (4 and 5) domains, are colored khaki, light
blue, pink, steel blue and deep blue, respectively. The HVGT and
KISKR motifs of GluRS are highlighted in purple. The ATP and
glutamate molecules in the GluRS catalytic pocket are shown in
green. (B) Overall structure of ERS/tRNA/ATP. The ATP and
tRNA^Glu molecules in the complex are shown in orange and
turquoise, respectively. These figures were produced using the
MOLSCRIPT (Kraulis, 1991) and RASTER3D (Merritt and Murphy,
1994) programs.
