Repellent Taxis in Response to Nickel Ion Requires neither Ni2+ Transport nor the Periplasmic NikA Binding Protein▿ Academic Article uri icon

abstract

  • 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+).
