The unique structure of Haemophilus influenzae protein E reveals multiple binding sites for host factors.
Haemophilus influenzae protein E (PE) is a multifunctional adhesin, involved in direct interactions with lung epithelial cells and host proteins, including plasminogen and the extracellular matrix proteins vitronectin and laminin. We recently crystallized PE and successfully collected X-ray diffraction data to 1.8 Å. Here we solved the structure of a recombinant version of PE and analyzed differen
