Part:BBa_K4613024

pQE-80L-T3-MCPA

The composite part was constructed to find an appropriate expression intensity to achieve balance between metabolic burden and detection efficiency. Moreover, we hope Mature Carboxypeptidase A (M-CPA), which can be found under https://parts.igem.org/Part:BBa_K4613013, can be expressed successfully in E. coli Nissle 1917 (EcN). We tried T5 lac promoter (from pQE-80L).
