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.
