Fig. 2: The PriA-CRR/PriB binding interface.

A Interface formed by PriA-CRR (magenta) and PriB (cyan). Interatomic distances are labeled. B Surface representations of the PriA-CRR/PriB interface colored by conservation (top, calculated using the ConSurf server72) or electrostatic surface potential (bottom). Interacting residues are noted. Since PriB is not well conserved across bacteria33, the calculation of PriA conservation was limited to 150 sequences from species containing priB genes.
