Aktivity determination using ABTS

File:TUM13 ABTS-oxidation.png

Figure 3:

The enzymatic activity of the purified laccae was determined by the ABTS-assay. In a first pre experiment the appropriate dilution factor was determined to 100-fold. The elution fractions obtained from size exclusion chromatography were diluted 1:100 in PBS and in an ELISA plate 100 µl of the enzyme and 100 µl of ABTS substrate were mixed and a kinetic measurement at 405 nm was performed. The absorption at 280 nm in the SEC chromatogramm (blue) identifies three main protein peaks, with a first peak corresponding to aggregated protein, a shoulder which also corresponds to higher molecular protein and a single peak which was proposed to be the monomeric laccase. The relative activity obtained for the different elution fractions was plotted in the same diagramm and shows a clear peak which matches the laccase peak in the SEC. Beside this major peak a second smaller peak of active fraction was visible which appeared in earlier elution fractions and might correspond to dimerized laccase. As the laccase is a secreted enzyme which also bears disluphide bonds it was produced in the cytoplasm and subsequently it was oxidized to form the proper disulphide bond. As this process might be only partial there is a possiblity for the formation of disulphid dimers. Never the less the fractions 14 to 17 were pooled for further experiments as they showed the highest enzymatic activity. The protein concentration of the pooled fraction was determined to 0.48 mg/ml after SEC.
