Figure 2. Electron density maps of vaccinia virus DNA topoisomerase I. (a) The original MIRAS map to 2.8 å used for tracing the amino-terminal fragment. The map is contoured at 1.0 σ. (b) 2F[o]– F[c] map at 1.6 å resolution of the cryo-cooled protein model, contoured at 1.2σ. Figure 2. Electron density maps of vaccinia virus DNA topoisomerase I.
