Usage

As a cell wall protein, GCW51 is often used as an anchor protein in Pichia pastoris to display some protein on the surface. By fusing GCW51 with the PETase, it can be displayed on the outer of the yeast cell wall.
  By expressing the fusion protein , PETase ,which can degrade macromolecular polymers into monomerswas, expressed on the surface of Pichia pastoris,. And the whole cell catalyst for the degradation of PET was obtained. Have the PETase fixed on the cell wall, on the one hand can improve the stability of PETase, on the other hand, it is easy to control the degradation reaction of PET and PETase recycling.

Biology

GCW51 was gained from Pichia pastoris GS115.As one of the Glycosylphosphatidylinositoled cell wall proteins (GPI-CWPs), GCW51 is located in the outer layer of yeast cell wall, its C terminal is oligo mannose glycosylated. Subsequently, the mannose chain of GCW21 connect with the β-1,6 dextranomer of inner cell wall layer by forming covalent connection, thus, the GCW21 is fixed in the outer layer of the cell wall protein.
PETase was found from a kind of microorganism living on PET as the main carbon source. It can degrade macromolecular polymers into monomers. Surface display can reveal the protein whose gene code is coalescing the gene code of target protein or polypeptide with the counterpart of ankyrin on the surface of the host cell wall to harvest the whole cell catalyst.
