NixA-F1v
Introduction
This part combines BBa_K5115071(NixA)with BBa_K5115085(F1v).
NixA is a high-affinity nickel transporter in helicobacter pylori. It belongs to the NiCoT family of transporters and facilitates the import of Ni²⁺ ions across the bacterial cytoplasmic membrane[1]. F1v is a signal transducer, binding NixA at its C end. The working procedure of F1v need the use of AP20187, which is a small molecule inducers. The addition of AP20187 to live cells expressing a F1v-tagged fusion protein induces self-association of the fusion protein by promoting the interaction of the dimerization domains.[2]

Usage and Biology
This part is built to introduce NixA into the E.coli and enhance its transporting abilities. We combined all of our parts concerning Nickel ions' transporting and detoxifying into BBa_K5115068(mineral nickel module), please visit this part to learn more details about our design and experiments.
