Figure 5

Electron micrographs of Soj nucleoprotein filaments. (A) Wild-type Soj+plasmid DNA (pU0J, a 2938 bp pUC19 derivative) in the absence of nucleotide. (B) Wild-type Soj+pU0J+ADP. (C) Wild-type Soj+linearised pU0J+ATP produces nucleoprotein filaments which are indistinguishable from those produced by (D) Soj D44A under the same conditions. (E) Nucleoprotein filaments formed by Soj D44A in the presence of relaxed, open circle pU0J+ATP. (F–H) High-magnification images of single nucleoprotein filaments, indicating a regular, perhaps helical arrangement.
