Hygromycin Resistance for Chlamydomonas reinhardtii (Phytobrick)

This level 1 composite part contains the PSAD-promoter (BBa_K3002001), the coding sequence of the hygromycin resistance cassette (BBa_K4806015)and the PSAD-terminator (BBa_K3002002). This part mediates resistance to hygromycin.


Constructs

Fig.1 Construct design
We designed 2 level 2 constructs containing the hygromycin resistance cassette using the modular cloning system (MoClo).


Here are the links to the built constructs:

  • 1. CYP3A4 tandem for expression together with the POR for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806214)
  • 2. CYP2D6 tandem for expression together with the POR for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806215)

Results

We detected the expression of CYP3A4 tandem together with the POR with HA-tag (BBa_K4806214) via immunoblotting.

Fig.2 Expression of CYP3A4 tandem together with the POR with HA-tag
(a)Level 2 MoClo construct for expression of the enzyme CYP3A4 tandem together with the POR containing the HA-tag was designed (see Fig.1 for part description)
(b) Picture of resulting western blot. The enzyme CYP3A4/POR is marked by a black arrow, the white arrow marks a cross reaction of antibodies. For reference, the UVM4 recipient strain and a strain expressing the HA-tagged ribosomal chloroplast 50S protein L5 (RPL5) were used as a negative and positive control, respectively

For detection the UVM4 strain was transformed with the construct in (a). 30 hygromycin-resistant transformants were cultivated in TAP medium and samples were taken after 3 days. Whole-cell proteins were extracted and analyzed by SDS-PAGE and immunoblotting using an anti-HA antibody. The expression of CYP3A4 (~ 57 kDa) and the POR (~77 kDa) is visible.
