Part:BBa_K3288057

light inducible expression of signal peptide (NSP4) fused PETase(28-290;W159H S238F)

BBa_K3288057 is a composite part in which BBa_K1075044, BBa_K3288007 and BBa_K3288012 are combined.

This part is compatible with RFC10.

Usage and Biology

After PETase and MHETase was analyzed based on protein structures, some of them were reported to be point mutated with increased enzyme activation. Our team checked PETase wild type, W159H/S238F, and S121E/D186H/R280A’s PET degradation activities to choose enzymes for PET degrading device. These enzymes were produced at 18 °C in LB (buffered 50mM BTP (pH8.5) for 24 hours. After centrifuged, we put PET disc into cleared media with no E.coli and reacted it for 24 hours at 40 degrees Celsius. Everyday, we replaced media with ones that has new PET degrading enzyme secreted. After 5 days, we washed PET disc and dried it up to measure the change in weight. Results showed that NSP4-PETase (S121E/D186H/R280A) degraded the most PET.
