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.

Pseudogenization of the cntQ permease confers distinct yersinopine-metal uptake selectivity in Yersinia species

Clémentine Laffont, Elizabeth Pradel, Laurent Ouerdane, Amélie Dewitte, Nicolas Oswaldo Gomez, Mathilde Tribout, Catherine Brutesco, Romé Voulhoux, Ryszard Łobiński, Florent Sebbane, Pascal Arnoux

The paper shows that a pseudogenization in the cntQ gene alters metal uptake specificity in Yersinia species, shifting from iron to zinc.
