Outer membrane autotransporter VirG/IcsA is a virulence factor from Shigella flexneri that acts as an adhesin and actin-polymerising factor during infection [1]. VirG/IcsA consists of three major domains: an atypical signal peptide at the N-terminal, followed by the passenger domain (presented on the cell surface) and a beta-domain that anchors the protein to the bacterial outer membrane. This entry represents the insertion domain (VID) that appears to be inserted into a continuous sequence of beta-helical coils [1].
