Part:BBa_K1189018
Human ferritin di-subunit with E coil w/ LacI promoter
This part was created by fusing the heavy chain and light chains (BBa_K1189024 BBa_K1189025) of human ferritin together. It is expressed under the lacI promoter (BBa_J04500) and has a his-tag for protein purification. An E-coil (BBa_K1189011) is included in order to allow binding of parts containing the respective K-coil (BBa_K1189010). Characterization of this part was done primarily with commercially purchased ferritin. This ferritin is structurally very similar to our recombinant ferritin and does not differ in its chemical properties (Figure 1).
This construct can be used as a reporter through a modification of the iron core to form Prussian Blue (Figure 2). The resulting molecule can then catalyze the formation of radicals from hydrogen peroxide, which can then cause a colour change in substrates such as TMB or ABTS (Figure 3).
