Anchor Protein 5105
Anchor Protein 5105 was selected from our predicted model and experimentally proved to anchor the protein on the cell surface.
Characterization
Construction of plasmid P-SS-yeGFP3-V5-5105-T
In our project, yeGFP was used to screen anchored proteins.
Fig.1 Structure of P-SS-yeGFP3-V5-5105-T.
Through restriction enzyme digestion verification and sequencing, the plasmid was successfully constructed (Figure 2).
Fig.2 Verification of recombinant plasmids by restriction enzyme digestion. M: DL 15000 DNA Marker； 1：P-SS-yeGFP3-V5-5105-T double enzyme digestion (Xba Ⅰ & EcoR Ⅰ)
After the plasmid was successfully constructed, it was introduced into the target strain Candida tropicalis . And then the expression of yeGFP and the position of fluorescent was confirmed with CLSM (Figure 3).
Fig.3 Representative images of yeGFP (P-SS-yeGFP3-V5-5105-T) expression. The yeast morphology observed under the bright field (Left). The yeast morphology observed under green fluorescence excitation wavelength (Middle). Merged image (Right).
