Mycobacterium tuberculosis Expresses a Novel Ph-Dependent Divalent Cation Transporter Belonging to the Nramp Family
Mammalian natural resistance-associated macrophage protein (Nramp) homologues are important determinants of susceptibility to infection by diverse intracellular pathogens including mycobacteria. Eukaryotic Nramp homologues transport divalent cations such as Fe(2+), Mn(2+), Zn(2+), and Cu(2+). Mycobacterium tuberculosis and Mycobacterium bovis (bacillus Calmette-Guérin [BCG]) also encode an Nram...
متن کاملCrystal Structure and Conformational Change Mechanism of a Bacterial Nramp-Family Divalent Metal Transporter.
The widely conserved natural resistance-associated macrophage protein (Nramp) family of divalent metal transporters enables manganese import in bacteria and dietary iron uptake in mammals. We determined the crystal structure of the Deinococcus radiodurans Nramp homolog (DraNramp) in an inward-facing apo state, including the complete transmembrane (TM) segment 1a (absent from a previous Nramp st...
متن کاملThe Divalent Cation Transporter Nramp in the Parasite Perkinsus Marinus: Genomic, Molecular, Structural, Functional and Evolutionary Aspects
Perkinsus marinus, the causative agent of Dermo disease in eastern oyster Crassostrea virginica has been a great hurdle for oyster population restoration along the atlantic and gulf coasts of USA. Iron was shown to be an essential element for P. marinus growth and virulence, but iron uptake pathways have not been elucidated. The Natural Resistance-Associated Macrophage Protein (Nramp), an iron ...
متن کاملDivalent cation transport by VNUT DIVALENT CATION TRANSPORT BY VESICULAR NUCLEOTIDE TRANSPORTER
The vesicular nucleotide transporter (VNUT) is a secretory vesicle protein that is responsible for the vesicular storage and subsequent exocytosis of ATP (Sawada, K. et al., (2008) Proc. Natl. Acad. Sci. U.S.A. 105, 11720-11724). Since VNUT actively transports ATP in a membrane potential (Δψ)-dependent manner irrespective of divalent cations such as Mg or Ca, VNUT recognizes free ATP as a trans...
