Repellent taxis in response to nickel ion requires neither Ni2+ transport nor the periplasmic NikA binding protein. Academic Article uri icon


  • Ni(2+) and Co(2+) are sensed as repellents by the Escherichia coli Tar chemoreceptor. The periplasmic Ni(2+) binding protein, NikA, has been suggested to sense Ni(2+). We show here that neither NikA nor the membrane-bound NikB and NikC proteins of the Ni(2+) transport system are required for repellent taxis in response to Ni(2+).
