Part:BBa_K4488019
Fusion of free-use GFPy with CBDcipA (cellulose-binding domain) at the C-terminal end with a linker
Analogous to part BBa_K4488012, with a yellow shifted GFP (see part BBa_K4488016)
Fusion protein of fuGFPy connected to a cipA cellulose-binding domain (CBD) via a flexible (GGGGS)3 linker. Analogous to part BBa_K4488013. This part was created using PCR with degenerate primers to mutate fuGFP-linker-CBDcipA to introduce the mutations in fuGFP creating the colour difference.
Usage and Biology
This part contains restriction sites making it suitable for traditional cloning with BamHI and XhoI as well as golden gate cloning with BsaI. The 2022 USYD Sydney Australia team was successful in expressing this protein with the BL21(DE)-pET28c(+) system. This fusion protein will fluoresce under UV and will bind to cellulose. Based on plate reader measurements, peak excitation occurs at ~490 nm and peak emission occurs at ~510 nm (Figure 1). fuGFPy-linker-CBDcipA binds to cellulose and is eluted with glucose (figure 2). Based on SDS-PAGE, elution with glucose from cellulose yields relatively pure samples as evidenced by a single band at ~46 kDa (figure 3).
