Schematic diagrams of the structure of AcrIC9 from R. capsulatus. (a) The AcrIC9 structure showing the three molecules detected in the crystallographic unit. (b) The structure of the AcrIC9 monomer. The color of the structure from the N- to the C-termini gradually changes from blue to red through the spectrum. (c) A topological representation of the AcrIC9 structure. The order of the secondary structure of α-helixes and β-sheets is shown in parentheses. (d) The surface electrostatic potential of AcrIC9 showing the surface electrostatic distribution: −8.2 kT e−1 (red) to 8.2 kT e−1 (blue). (e) Superimposition of the three molecules in the same crystallographic unit cell. (f) B-factor distribution for the AcrIC9 structure. The structure is shown as a putty representation. (g) Structural comparison of the crystal structure (green) with the predicted structure (gray) generated as a cartoon by using AlphaFold2. The main parts of the backbones that are not perfectly aligned are indicated by red-dashed boxes.
