PmrA-PmrB(N-term) from Salmonella

This is N-terminal part of PmrA-PmrB two-component system native to Salmonella enterica. PmrA-PmrB two-component system is native to Salmonella enterica and in it's native state it is responsible for chemotaxis. PmrB is a transmembrane protein with iron binding peptide on it's extracellular loop. When PmrB binds iron (III) iron, it's intracellular domain gains kinase activity and phosphorylates PmrA, which subsequently binds to pmrC promoter and induces expression of chemotaxis CheZ protein. In this part iron binding tag on the extracellular loop was exchanged with a lanthanide binding tag (LBT), to allow PmrA-PmrB two-component system to respond to lanthanide ions. In this part, PmrB protein is truncated just before iron binding tag, which enables one to put any desired tag between two parts of PmrB, to construct a detecting system based on PmrA-PmrB system.
