Figure 4

Study of deletion mutants in the linker region joining the N-domain to D1. A shows a schematic domain map of ClpA with the amino acid sequence of the N-domain/D1 linker. The amino acids deleted in the Δ10 and Δ15 mutants are colored in green and red respectively. B, Cryo-electron micrograph of ClpA-Δ10/ClpP complexes. Arrows point to some complexes on which N-domain densities are visible at the apical surface of ClpA. C & E, averaged side-views of 1:1 complexes of ClpP with the Δ10 and Δ15 mutants of ClpA. The arrowhead in each panel marks the location occupied by the still-mobile N-domains. D & F, side-view variance maps of complexes with the Δ10 and Δ15 mutants.
