== Function ==
[https://www.uniprot.org/uniprot/HASA_SERMA HASA_SERMA] Can bind free heme and also acquire it from hemoglobin. Conveys heme from hemoglobin to the HasR receptor which releases it into the bacterium. HasR alone can take up heme but the synergy between HasA and HasR increases heme uptake 100-fold.<ref>PMID:7937909</ref> <ref>PMID:9171402</ref>
