AOX1-Kozak-PHO1-SLAC-His tag-AOX1 Terminator

PHO1 is one of three repressible acid phosphatases, a glycoprotein that is transported to the cell surface. SLAC can catalyze lignin.

Characterization

This is a four section for degrade and transfer lignin part.

Figure1. AOX1-PHO1-SLAC-His tag.

SDS-PAGE

We run the SDS-PAGE to check whether PHO1 help the enzyme transfer to the extracellular. As the figure shows, we get the protein type about 35 KDa which means the SDS-PAGE is successful.

Figure3:the SDS-page result shows that Pichia pastoris have successfully secrete SLAC protein into superfluous liquid.


Enzyme Activity

We use ABTS to detect the enzyme activity. As the figure shows, the solution turns green, which confirm the enzyme activity.

Figure4:these four pictures shows the enzyme activity changes with the time. The four kinds of Pichia pastoris have the different curve, and the most activity strain is FLO10-apro, PHO5apro shows a more delayed increase on enzyme activity.
