PSAD-promotor for Chlamydomonas reinhardtii (Phytobrick)
This basic part contains the coding sequence of the PSAD-promotor (A1-B1). This part is codon-optimized for Chlamydomonas reinhardtii and was built as part of the CYPurify Collection. In combination with a coding sequence like CYP3A4 (BBa_K4806000) and a terminator like tRPL23 (BBa_K3002006), this level 0 part leads to expression of your target protein (Einhaus et al., 2021). To detect the target protein a tag like HA-tag (BBa_K3002017) is recommended.
Constructs
We designed 4 level 2 parts containing the PSAD-promotor 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 PSAD-promotor the constructs either contain the hygromycin (BBa_K4806100), paromomycin (BBa_K4806101) or the spectinomycin resistance cassette (BBa_K3002000), the CTPPSAD transit peptide to the chloroplast (BBa_K4806014), 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.
(a)Level 2 MoClo construct for expression of the enzyme CYPCamC containing the HA-tag was designed (see Fig.1 for part description)
(b) Picture of resulting western blot. The enzyme CYPCamC 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 CYPCamC (~ 47 kDa) is visible.
