A Gram-negative bacterium that spans the commensal-pathogen spectrum, with pathogenic variants (UPEC, STEC, EHEC) deploying nickel-dependent enzymes as virulence factors. E. coli is the model organism for nickel transport biology -- the NikABCDE system was first charact…
Specialized membrane proteins that import nickel into bacterial cells, supplying the essential cofactor for virulence enzymes including urease, NiFe-hydrogenase, and Ni-glyoxalase. Because mammals produce no known nickel-requiring proteins, these transporters represent …
