PF06438Heme-binding protein A (HasA) (HasA)Heme-binding protein A (HasA)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. ...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].
