Major facilitator transporter involved in ferrichrome (FC) and ferrioxamine B (FOB) uptake (PubMed:26929401). Highly expressed under low-iron conditions and down-regulated under high-iron conditions (PubMed:26929401). Expression is regulated by hapX under low-iron conditions (PubMed:26929401). Leads to lower ferrichrome (FC) and ferrioxamine B (FOB) uptake activities, which are reduced to approximately 60% and 50% of the wild-type activities, respectively (PubMed:26929401). Belongs to the major facilitator superfamily.
