Cutinase-Like Enzyme

Encodes a lipase that hydrolyses compound polylactic acid.

Source organism: Cryptococcus sp. strain S-2

Characterisation

Our Cutinase-like enzyme (CLE) construct contains sfGFP within an operon and therefore fluorescence can be utilised to determine if expression is being induced by addition of Xylose.

CLE growth assay. E. coli (MG1655) transformed with CLE BBa_K1149009 were grown with either 0% or 2% Xylose to induce CLE and sfGFP expression. Induction with xylose shows growth inhibition. Ideally you would normalise the fluorescence with OD600 to give fluorescence/cell in order to get the actual difference in induction expression. A two-tailed t-test shows that p = 0.4308 > 0.05, therefore there is no statistical difference between induced and uninduced. Growth was at 37°C with shaking. Error bars are SEM, n=4. Figure made by Imperial College London 2013 iGEM.

CLE induction assay. E. coli (MG1655) transformed with CLE BBa_K1149009 were grown with either 0% or 2% Xylose to induce CLE and sfGFP expression. CLE induction does not seem to increase the amount of fluorescence emitted by the GFP. Growth was at 37°C with shaking. Error bars are SEM, n=4. Figure made by Imperial College London 2013 iGEM.

Conclusion: There is no growth inhibition caused by induction, nor is there any significant fluorescence.
