P-ss-yeGFP-V5tag-Anchor protein 4609-T

Our part BBa_K33829010 is a contribution to the part-reporter GFP BBa_K3402000 (iGEM20_Jiangnan_China).

Characterization

Construction of plasmid P-SS-yeGFP3-V5-4609-T

In our project, yeGFP was used to screen anchored proteins.


Fig.1 Structure of P-SS-yeGFP3-V5-4609-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-V5-4609-T double enzyme digestion (Xba Ⅰ & EcoR Ⅰ)

The plasmid was linearized and transferred to Candida tropicalis . The transformants were screened out by uracil deficiency. And then cultivated the transformants and observed the fluorescence with confocal laser scanning microscopy (CLSM). As a result, green fluorescence was observed on the cell surface, indicating that yeGFP was expressed and the anchor protein 4609 performed well. (Figure 3).


Fig.3 Representative images of yeGFP (P-SS-yeGFP3-V5-4609-T) expression. The yeast morphology observed under the bright field (Left). The yeast morphology observed under green fluorescence excitation wavelength (Middle). Merged image (Right).
