Abstract

The Omp85/YaeT family of proteins, which are conserved from bacteria to human, catalyzes insertion and assembly of proteins in the outer membrane. The structure consists of a transmembrane β-barrel domain and a soluble polypeptide-transport-associated (POTRA) domain. The POTRA domain is critical for substrate recognition and perhaps substrate folding, while the β-barrel domain assists in membrane insertion. The resolution of the crystal structure of the POTRA domain of the Escherichia coli YaeT protein provides a possible molecular mechanism by which the diverse group of substrates is recognized. Knowledge gained from the crystal structure may also spur the development of a novel class of chemotherapeutic inhibitors.
