FIGURE 2.

Structural comparison of Bc-TubZ with Bt-TubZ and Cb-TubZ (A) and with M. jannaschii FtsZ (B). A, superposition of GTPγS-Bc-TubZΔ (green), GTPγS-Bt-TubZ (cyan; Protein Data Bank code 3M89), and apo-Cb-TubZ (purple; code 3V3T). GTPγS is shown as sticks. B, superposition of GDP-Bc-TubZΔ (green) and FtsZ (pink; code 1W59). The H0 and H1 helices are shown as cylinders. Structures are superimposed using the N-terminal GTPase domain. The views are in the same orientation as in Fig. 1A. Mj, M. jannaschii.
