Figure 4. Ribbon tracing of the GTPase domain of YloQ (A)
and Era (B). The ribbons are colour-ramped from the N terminus
(blue) to the C terminus (red). The secondary structure elements
are labelled. In YloQ, the break in the ribbon connecting a4 to
b12 is caused by residues 187-205 being disordered and absent
from the model. Topology diagrams of YloQ (C) and Era (D)
illustrating the circular permutation of the GTPase domain.
