Fig. 7: Superimposed molecular structures of Redβ, λExo and DNA.

This molecular scene was created by piecing four structures together. These include the structure of λExo bound to DNA⁶⁶ (4WUZ, three λExo monomers represented as surfaces in different shades of blue and DNA in green); the structure of λExo bound to the C-terminal domain of Redβ⁵³ (6M9K, C-terminal domain of Redβ shown in light purple and λExo superimposing with the one in 4WUZ is hidden); the Redβ₁₇₇ model (DNA in black and protein in dark purple); and the AlphaFold prediction for the full-length Redβ⁵⁴ (the α7 helix shown in pink and the N- and C-terminal domains superimposing with the corresponding domains in our Redβ₁₇₇ structure and 6M9K, respectively, are hidden).
