PnuC-GFP-Pm associated sequence

Design

PnuC codes for the transporter that transport NR into the cell and transport NMN out of the cell. We endeavored to express pnuC on the cell membrane of kluyveromyces marxianus, a close relative of Saccharomyces cerevisiae, to pump NMN out. However, pnuC we use is derived from Bacillus mycoides. Hence, to express pnuC on the cell membrane of kluyveromyces marxianus requires a signal peptide called plasma membrane associated (PMassc) sequence. PMassc sequence is derived from the last fifty amino acids of Gap1 transporter of Saccharomyces cerevisiae, guiding Gap1 transporter to the cell membrane of Saccharomyces cerevisiae. In our project, we fuse PnuC, GFP, and PMassc sequences together, so PnuC can be expressed on the plasma membrane of Kluyveromyces marxianus and we are able to observe it.

Test

Then, we integrated this construct into the pklac2 expression vector and integrated the plasmid into the genome of Kluyveromyces maraxianus. To test the effectiveness of PMassc sequence on pnuC, we put the engineered k. marxianus under the fluorescence microscope and observe fluorescence on the cell membrane of K. marxianus, indicating the PMassc sequence can make proteins be expressed on cell membrane of kluyveromyces marxianus.
