UniProtKB description:  Part of a high affinity heme acquisition system (PubMed:34725337). Functions as a hemophore that acquires heme from human hemoglobin and delivers the heme to its cognate receptor, HphR, facilitating transport of heme across the bacterial outer membrane (PubMed:34725337). Apo HphA interacts specifically with human hemoglobin and steals heme through a passive process probably due to its high affinity for heme (PubMed:34725337). It can also acquire heme complexed to human serum albumin (PubMed:34725337). Plays a supporting role for full virulence, acting as an accessory factor that enhances the process of heme uptake (PubMed:34725337).
