CTPPSAD-transit peptide for Chlamydomonas reinhardtii (Phytobrick)

This basic part contains the coding sequence of the CTPPSAD-transit peptide to the chloroplast (B2). This part is codon-optimized for Chlamydomonas reinhardtii and was built as part of the CYPurify Collection. In combination with the PSAD-promotor (BBa_K4806010) and a terminator like tRPL23 (BBa_K3002006), this level 0 part leads to expression of your target protein in the chloroplast (Einhaus et al., 2021). To detect the target protein a tag like HA-tag (BBa_K3002017) is recommended.


Constructs

Fig.1 Construct design
We designed 4 level 2 constructs containing the CTPPSAD-transit peptide using the modular cloning system (MoClo).


Here are the links to the built constructs:

  • 1. The POR gene for expression in the chloroplast for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806212)
  • 2. CYP2D6 gene for expression in the chloroplast for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806208)
  • 3. CYPCamC gene for expression in the chloroplast for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806217)
  • 4. CYP3A4 gene for expression in the chloroplast for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806203)

These constructs were transformed into Chlamydomonas reinhardtii. Besides the CTPPSAD-transit peptide the constructs either contain the hygromycin (BBa_K4806100), paromomycin (BBa_K4806101) or the spectinomycin resistance cassette (BBa_K3002102), the PSAD-promotor transit (BBa_K4806010), either the POR (BBa_K4806003), CYP2D6 (BBa_K4806001), CYPCamC (BBa_K4806002) or the CYP3A4 coding sequence (BBa_K4806000), the HA-tag (BBa_K3002017 for detection and the tRPL23-terminator (BBa_K3002006).

Results

We tried to detected the expression of the POR, CYP2D6, CYPCamC and CYP3A4 targeted to the chloroplast with HA-tag (BBa_K4806212, BBa_K4806208, BBa_K4806217, BBa_K4806203) via immunoblotting.

Fig.2 Expression of the POR, CYP2D6, CYPCamC and CYP3A4 in the chloroplast
(1a-4a) Level 2 MoClo construct for expression of the enzyme POR, CYP2D6, CYPCamC and CYP3A4 containing the CTPPSAD transit peptide to the chloroplast were designed (see Fig.1 for part description)
(1b-4b) Picture of resulting western blots. The enzymes are marked by a black arrow, the white arrow marks cross reactions 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 (1a-4a). 30 antibiotic resistant transformants (depending on the construct) 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 the POR (~77 kDa), CYP2D6 (~56 kDa) CYPCamC (~ 47 kDa) and CYP3A4 (~57 kDa) is not visible.
