Description
To certify success in constructing pSB1C3-CaO19, digestion assay using Eco RI and Pst I was performed. The product digested by Eco RI and Pst I was around 900bp as predicted 912bp of CaO19.
Figure 1. Digestion assay of pSB1C3-CaO19.
In our project, Cao19 gene is cloned into expression vector pET28a and induced by IPTG. The optimized induction condition is 0.3mM IPTG, 180rpm in 25℃ for 16h. The enzyme is further purified by affinity chromatography.
Cao19 activity was determined by measuring the increase of absorbance at 260 nm, corresponding to the maximum absorbance of product muconic acid. The standard assay of enzyme activity was performed by addition of 2μ (68g/ml) of 1,2-CTD to 998μ of assay solution (PBS containing 20M FeSO4 and 0.1 mM of catechol) at 25°C.
