3 kDa with approximately 90% purity after gel filtration chromatography. Because ArlR was biologically active after its purification, it accepted the corresponding phosphorylated histidine kinase phosphate group and bound to the analogous DNA sequence. The binding constant between ArlR and the corresponding histidine kinase was about 2.1 μM, whereas the binding constant between ArlR and its operon was 6.4 μM. Altogether, these results illustrate an effective expression and purification method for the novel two-component system prote
