Transports the metallophore pseudopaline, which is involved in the acquisition of nickel and zinc, and thus enables bacterial growth inside the host, where metal access is limited. Is probably involved in the export of pseudopaline. Is part of the operon cntOLMI that is negatively regulated by zinc level through the Zur repressor, which leads to transcriptional activation of this operon under zinc depletion. Mutant shows a large decrease in the extracellular pseudopaline level, with a concomitant increase in the intracellular space. Mutant is unable to grow in airway mucus secretions (AMS) and is impaired in iron accumulation in this media supplemented with iron. Belongs to the EamA transporter family.
