Cyanochelin uptake reveals an exclusively cyanobacterial class of AMIN-domain TonB-dependent transporters
This study functionally characterise the import system of cyanochelin B, a photolytic β-hydroxy aspartate siderophore produced by several filamentous cyanobacteria, and reports the first functional heterologous expression of a cyanobacterial TonB-dependent transporter and establishes Synechocystis as a promising platform for cyanobacterial xenosiderophore-uptake studies.
