    The integral outer membrane protein X (OmpX) from Escherichia coli belongs to a family of highly conserved bacterial proteins that promote bacterial adhesion to and entry into mammalian cells. Moreover, these proteins have a role in the resistance against attack by the human complement system. Here we present the first crystal structure of a member of this family.
