Figure 5.
Figure 5 Crystal structure of Tth Gfh1. (A) Ribbon
representation of Gfh1 structure is shown in two orthogonal
views (left and central panel). The location of the two domains,
NTD and CTD, and the four Asp residues of NTD loop are
indicated. The structure of E. coli GreA (Stebbins et al, 1995)
is shown for comparison (right panel). (B) Superposition of the
structures of E. coli GreA (orange) and Tth Gfh1 (blue) as C[
 ]trace.
Left panel shows the alignment by NTD and central panel shows
alignment by CTD. Overall, the molecules superimposed well with
r.m.s. deviation of the C[ ]atoms=1.8
Å with more than 90% equivalences. The rotation axis of
the CTD is indicated. Right panel shows aligned NTDs, rotated by
60° counterclockwise around the NTD axis from the view shown
in the left panel.
