RBS-PhoA-His6tag-pNBEst13-Myctag-EstA

RBS-PhoA-His6tag-pNBEst13-Myctag-EstA is a long name for a long protein construct. It is a fusion protein which is secreted into the peri plasma in order to be integrated into the outer membran. When the phoA signal sequence is cut off, the N-terminus is formed by our pNB-Est13. This esterase shows actitivty towards PET and is anchored onto the cell by its inactive EstA membrane anchor.

Annotation: This site is about the construct and composition of our chimeric protein BBa_K808030. For any information about its expression rate or enzyme activity please visit BBa_K808032


Usage and Biology

Composition

Our fusion protein BBa_K808030 is highly chimeric. It consists of parts from three different bacteria, which are the following (starting from N-terminus to C-terminus):

  • PhoA (BBa_K808028) is responsible for the peri plasmatic expression of our chimeric protein. This is highly important because once expressed into peri plasma, our construct will self-install into the outer membrane. PhoA is native to E.coli
  • pNB-Esterase 13 (BBa_K808026) is the the catalytical domain of BBa_K808030. It derives from an esterase of Bacillus licheniformis.
  • EstA (BBa_K808027) serves as a membrane anchor but is an inactive and membrane bound esterase mutant deriving from Pseudomonas aeruginosa
