Part:BBa_K1149006
pelB-pulA-flag expression
Expression of a plastic degradation enzyme from Pseudomonas fluorescens under arabinose inducible promoter. The protein in codon optimized for expression in ecoli, is flag tagged and has an Nterminal pelB tag for secretion. Encodes polyurethane esterase, break down ester bonds in polyurethane.
PUR degradation by esterase:
Characterisation
Our PulA construct was tested for growth upon induction by addition of Arabinose.
PulA growth assay. E. coli (MG1655) transformed with PulA (BBa_K1149006) were grown with either 0 μM or 6 μM Arabinose to induce PulA expression. There was no growth inhibition as p = 0.7648 > 0.05, therefore induction did not cause significant growth decrease. Growth was at 37°C in LB 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 in PulA.
