TonB-dependent Transporters of Fe-petrobactin in Marinobacter nauticus and Southern Ocean bacteria

Sophie Nolivos, Rhea Thoppil, Florence Hakil, Audrey Guéneuguès, Philippe Catala, Katarzyna Kińska, Ryszard Łobiński, Stéphane Blain, Ingrid Obernosterer, R Grimaud

The paper identifies two TBDTs in Marinobacter nauticus that mediate Fe-petrobactin uptake, showing distinct regulatory mechanisms and evolutionary trajectories, and demonstrates Fe-petrobactin's role in stimulating prokaryotic growth in Southern Ocean communities.
