Part:BBa_K3002127
Level 1 – Hygromycin Resistance Gene for Chlamydomonas reinhardtii (Phytobrick)
This composite part contains the PSAD-promoter (BBa_K3002001) in combination with the PSAD-Terminator (BBa_K3002002) and the coding sequence of the Hygromycin resistance (BBa_K3002013) plus the MoClo connectors for positions B2-B3 (BBa_K3002303) and B5-B6 (BBa_K3002305). This part mediates resistance to hygromycin.
For successful expression and transformation, a reliable selection marker is needed. The hygromycin cassette allows the selection of positive transformants on hygromycin and can be used for a Co-transformation together with aadA construct. The MUT-PETase and MHETase are both seen after the co-transformation. An ARS secretion signal is upstream to the MUT-PETase gene and the cCA secretion signal upstream to the MHETase gene. The MUT-PETase is crucial for the degradation of PET into terephthalic acid and ethylene glycol.
The Kaiser Collection
We are proud to present our very own MoClo part collection for C. reinhardtii - the Kaiser collection.
These 20 Parts are specifically designed and codon optimized for Chlamydomonas. Among them are regulatory elements, antibiotic resistances, resistance cassettes, secretion signals and tags. These parts were tested and optimized thoroughly and we can guarantee that they work 100%. With these, expression and secretion in Chlamy will be a success. Because this is a MoClo collection, the parts are highly standardized for worldwide application. The combination with other part collections works fast and easy. While in MoClo, nomenclature is a bit different from the iGEM BioBricks, it is quickly explained:
Level 0 parts are equivalent to basic parts, e.g. Promoters, coding sequences, etc.
Level 1 parts are combinations of basic parts and usually form functional transcription units.
Level 2 parts are combinations of Level 1 parts, in case you want to transfer multiple transcription units at once. For example, you can pair your gene of interest with a selection marker.
The great thing about the Kaiser Collection and MoClo is that the ligation works in a one pot, one step reaction, as the Type IIs restriction enzymes cut out their own recognition sites. This way, multiple constructs can be combined linearly in a fixed order to create complex structures. This is ensured by the standardized overlaps that assign the parts one of 10 positions in the final constructs. After trying MoClo once, you won’t go back to traditional ligation. It is incredibly easy and reliable. For this reason, we believe that our Kaiser Collection will strike a significant chord, as the future lies in standardized, easy to use methods such as MoClo.
