OMIT maps of GDP and GTP in EcFtsZ(L178E) structures. (a) Close-up of the GDP bound in the N-terminal subdomain pocket in EcFtsZ(L178E). The helices, strands and loops are colored cyan, red and magenta, respectively. The blue mesh corresponds to the Fo − Fc OMIT map (in which the GDP was removed) contoured at 3.5σ around the GDP. (b) Close-up of the GTP in the EcFtsZ(L178E)–GTP complex with the protein secondary-structural elements colored as in Fig. 2(a). The Fo − Fc map is shown as a blue mesh and is contoured at 2.9σ. |
