POR gene for expression in the chloroplast for Chlamydomonas reinhardtii (Phytobrick)
This composite part contains the PSAD-promotor (BBa_K4806010), the CTPPSAD-transit peptide (BBa_K4806014), the POR coding sequence (BBa_K4806003), the HA-tag (BBa_K3002017)* for detection and the tRPL23-terminator (BBa_K3002006)*. This part is codon-optimized for Chlamydomonas reinhardtii and was built as part of the CYPurify Collection. This level 2 part leads to potential detoxification of specific chemicals (Ohkawa & Inui, 2015).
Construct
This construct was designed using the modular cloning system (MoClo).
The resistance cassette for hygromycin is already built in the level 2 vector 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 confirmed that this construct is built correctly via agarose gel electrophoresis.
We digested this level 2 MoClo part with the restriction enzymes NotI and EcoRI.
The test digest in Fig.2 was compared to an in-silico digest. Together with the sequencing results we were able to demonstrate that our construct was built correctly.
We tried to detected the expression the POR targeted to the chloroplast with HA-tag via immunoblotting.
(a)Level 2 MoClo construct for expression of the POR containing the CTPPSAD-tranist peptide with HA-tag was designed (see Fig.1 for part description)
(b) Picture of resulting western blot. 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 the POR (~ 77 kDa) is not visible.
