AβSAP(i)-promotor for Chlamydomonas reinhardtii (Phytobrick)
This basic part contains the coding sequence of the AβSAP(i)-promotor (A1-B2). 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 20 level 2 constructs containing the AβSAP(i)-promotor using the modular cloning system (MoClo).
Here are the links to the built constructs:
- 1. CYP2D6 gene with HA-tag for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806206)
- 2. CYP2D6 gene with mStop for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806207)
- 3. CYP9Q3 gene with HA-tag for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806222)
- 4. CYP9Q3 gene with mStop for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806223)
- 5. CYP9Q3 gene with mNeonGreen for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806224)
- 6. The POR gene with FLAG-tag for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806210)
- 7. The POR gene with HA-tag for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806209)
- 8. The POR gene with mStop for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806211)
- 9. The POR gene with mNeonGreen for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806213)
- 10. CYP3A4 tandem for expression together with the POR for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806214)
- 11x. CYP2D6 tandem for expression together with the POR for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806215)
- 12. CYP2D6 gene with FLAG-tag for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806206)
- 13. CYPCamC gene with HA-tag for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806216)
- 14. CYP81A10V7 gene with HA-tag for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806219)
- 15. CYP81A10V7 gene with mStop for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806220)
- 16. CYP81A10V7 gene with mNeonGreen for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806221)
- 17. CYP3A4 gene with FLAG-tag for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806201)
- 18. CYP3A4 gene with mStop for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806202)
- 19. CYP3A4 gene with HA-tag for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806200)
- 20. CYP3A4 gene with mNeonGreen for Chlamydomonas reinhardtii (Phytobrick) (BBa_K4806204)
These constructs were transformed into Chlamydomonas reinhardtii. Besides the AβSAP(i)-promotor the constructs either contain the CYP2D6 (BBa_K4806001), CYP9Q3 (BBa_K4806004), the POR (BBa_K4806003), CYPCamC (BBa_K4806002), CYP81A10V7 (BBa_K4806005) or the CYP3A4 coding sequence (BBa_K4806000), either the HA-tag (BBa_K3002017)*, the FLAG-tag (BBa_K4806012) or mNeonGreen (BBa_K4806006) for detection or mStop (BBa_K4806009) and the tRPL23-terminator (BBa_K3002006)*. The resistance cassette for paromomycin, spectinomycin or hygromycin is already built in the level 2 vector pMBS808/pMBS807/pMBS810 we are using. The usage of this vector allows the direct assembly of level 0 parts to level 2 constructs, facilitating the cloning time (Niemeyer & Schroda, 2022).

Results
We detected the expression of the POR, CYP3A4 tandem with the POR, CYPCamC and CYP3A4 with HA-tag (BBa_K4806209, BBa_K4806200, BBa_K4806216, BBa_K4806214) via immunoblotting.
(1a-4a) Level 2 MoClo construct for expression of the enzyme POR, CYP3A4 tandem with the POR, CYPCamC and CYP3A4 containing the HA-tag 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), CYPCamC (~ 47 kDa) and CYP3A4 (~57 kDa) is visible.
We detected the expression of the POR, CYP2D6 and CYP3A4 with FLAG-tag (BBa_K4806210, BBa_K4806206, BBa_K4806201 via immunoblotting.
(1a-3a) Level 2 MoClo construct for expression of the enzyme POR, CYP2D6 and CYP3A4 containing the FLAG-tag were designed (see Fig.1 for part description)

For detection the UVM4 strain was transformed with the construct in (1a-3a). 30 antibiotic resistant transformants (depending on the construct) were cultivated in TAP medium and samples were taken after 3 days.
