Part:BBa_K4806213
POR gene with mNeonGreen for Chlamydomonas reinhardtii (Phytobrick)
This composite part contains the AβSAP(i)-promotor (BBa_K4806013), the coding sequence of the POR (BBa_K4806003), mNeonGreen (BBa_K4806006) and the tRPL23-terminator (BBa_K3002006)*. This part is codon-optimized for Chlamydomonas reinhardtii and was built as part of the CYPurify Collection.
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 NheI and EcoRV.
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.

The CYurify Collection
The world is at a crossroad. We must decide now how we want to continue living in order to survive. To contribute to this cause, we proudly present our CYPURIFY Collection for Chlamydomonas reinhardtii. The contamination of our water with toxic substances is on the rise, damaging ecosystems and eventually impacting us humans. We see it as our duty to take action.
To accomplish this, we designed 23 level 0, 9 level 1 and 24 level 2 parts for bioremediation of toxic wastewater using Modular Cloning. At heart of this collection are the Cytochrome P450 enzymes. Some of these monooxygenases are already used in synthesis or in medicine. We aimed to take a further step in research by expressing these enzymes in Chlamydomonas for the first time.
Chlamydomonas reinhardtii is the perfect fit for our system as a phototrophic organism with cost-effective and sustainable cultivation. Additionally, this organism is well-studied and easy to transform. We have access to a vast library of preexisting parts, all compatible with Modular Cloning.
Modular Cloning is a cloning method based on the Golden Gate System. What makes it unique is the ability to assemble entire genes in a single reaction. This is made possible by using type IIS restriction enzymes, which cut outside their recognition sequence, effectively removing it after ligation into the target vector. Therefore, the reaction proceeds in a specific direction. The parts are divided into level 0,1 and 2. Level 0 parts are basic components such as promotors, terminators or tags. Level 1 parts are combinations of these level 0 parts, forming transcriptional units. Level 2 parts are combinations of level 1 parts, allowing the expression of multiple genes simultaneously. Level 0 parts are assigned one of 10 positions, with standardized overhangs between them, enabling the exchange of parts between laboratories.
With our collection, we aim to contribute to environmental protection. This collection is infinitely expandable with new CYPs that can degrade other toxic substances. So, what are you waiting for?
