Purification of the Campylobacter jejuni Dps protein assisted by its high melting temperature.
Protein Expression and Purification 2015 July
Dps proteins (DNA binding protein from starved cell) form a distinct group within the ferritin superfamily. All Dps members are composed of 12 identical subunits that assemble into a conserved spherical protein shell. Dps oxidize Fe(2+) in a conserved ferroxidase center located at the interface between monomers, the product of the reaction Fe(3+), is then stored inside the protein shell in the form of non-reactive insoluble Fe2O3. The Campylobacter jejuni Dps (CjDps) has been reported to play a plethora of functions, such as DNA binding and protection, iron storage, survival in response to hydrogen peroxide and sulfatide binding. CjDps is also important during biofilm formation and caecal colonization in poultry. In order to facilitate in vitro characterisation of CjDps, it is important to have a simple and reproducible protocol for protein purification. Here we report an observation that CjDps has an unusual high melting temperature. We exploited this property for protein purification by introducing a thermal treatment step which allowed achieving homogeneity by using only two chromatographic steps. Gel filtration chromatography, circular dichroism, mass spectrometry, DNA-binding and iron oxidation analysis confirmed that the CjDps structure and function were unaffected.
