pelB-pueA expression
This part expresses a plastic degradation enzyme under the control of xylose inducible promoter.
The enzyme is the pueA from Pseudomonas chlororaphis, that encodes carboxylesterase that breaks down ester bonds in polyurethane. This protein is [http://onlinelibrary.wiley.com/doi/10.1111/j.1574-6976.2010.00231.x/full naturally extracellular], it has a C-terminal secretion signal located downstream of a domain containing three glycine-rich repeats. These glycine-rich repeats are nonapeptide motifs involved in Ca2+-binding found in proteins secreted via type I systems. It uses the RTX system. To ensure secretion in E.coli, we have also added a pelB seretion tag to the N-terminal. We also added a 6xHistidine tag for Western blotting and protein purification purposes.
