Usage
The anchor of a new autotransportermetthat diated bacterial surface display system BrkAu to Display based on the structure of BrkA. The unique characteristic of BrkA is that the cleaved passenger domain remains adhered on the bacterial surface, which is conducive to keep the displayed exogenous proteins associated onto the cell, thus, the functionalized bacteria can be recycled/re-used conveniently.Now we hope to display our PETase on the surface of E. coli by using it.
Biology
PETase was found from a kind of microorganism(Ideonella sakaiensis 201-F6) living on PET as the main carbon source. It can degrade macromolecular polymers into monomers. PETase is the only enzyme found in bacteria which can degrade PET.
Autotransporter BrkA (Bordetella serum-resistance killing protein A )is from Bordetella pertussis,PETase is the passenger between the signal peptide and the anchor.
