Usage

As a cell wall protein of Pichia pastoris, GCW51 is often used as an anchor protein in Pichia pastoris surface display system because of its stable connection with the dextranomer in cell wall.  By fusing GCW51 with the target protein expression, the target protein can be displayed on the outer of the yeast cell wall. 
By expressing the fusion protein of GCW51 protein and PETase, PETase was expressed on the surface of Pichia pastoris, and the whole cell catalyst for the degradation of PET was obtained. We made the PETase fixed on the cell wall, which can improve the stability of PETase, and is easy to control the degradation reaction of PET and PETase recycling.

Biology

This part 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 GCW51 connect with the β-1,6 dextranomer of inner cell wall layer by forming covalent connection, thus, the GCW51 is fixed in the outer layer of the cell wall protein.
