Figure 5. Superimposition of the GTPase domains of YloQ and
the Ras-GDPNP complex (PDB accession, 1LF0) as a stereo view.
The ribbon tracing of YloQ is presented in cyan, that for Ras is
in yellow. The guanine nucleotide bound in Ras is displayed in
ball-and-stick format in magenta. The broken line indicates the
disordered region in the YloQ molecule. The G1 (P-loop), G2
(Switch I), G3 (Switch II) and G4 (guanine specificity motif)
segments of YloQ are coloured red. The structures were
overlapped initially in the program MOLREP,[35.] and
subsequently adjusted manually to emphasise similarities and
differences in the P-loop region.
