Free iron is limited in vertebrate hosts, thus an alternative to siderophores has been developed by pathogenic bacteria to access host iron bound in protein complexes. HasA is a secreted hemophore that has the ability to obtain iron from hemoglobin. Once bound to HasA, the heme is shuttled to the receptor HasR, which releases the heme into the bacterium [1].	Domain
