AffiPmrB

This part is modified from PmrB receptor in PmrB/A two-component system in E.coli. PmrB uses an iron (III)-binding motif to sense the environment(Chen & Groisman, 2013). The extracellular iron (III)-binding motif of pmrB receptor is replaced with another protein named affibody to construct this part. Affibody is a protein that can recognize Fc fragment of antibody(Stahl et al., 2017). This part is used to recognize the extracellular antibody signal and start the downstream signal transduction system.
In Tsinghua 2022 project, it was used in affipmrABC（BBa_K4307028) system.
