Outer Membrane Protein X (OmpX) WT gene
The integral outer membrane protein X (OmpX) from Escherichia coli belongs to a family of highly conserved bacterial proteins. Its role is to promote bacterial adhesion and entry into mammalian cells. These proteins have a role in the resistance against attack by the human complement system.(1)
Structure
OmpX consists of an eight-stranded antiparallel all-next-neighbor beta barrel. The structure shows two girdles of aromatic amino acid residues and a ribbon of nonpolar residues that attach to the membrane interior. The core of the barrel consists of an extended hydrogen-bonding network of highly conserved residues. OmpX thus resembles an inverse micelle. (1)
