MT-IEE5-arsC
Background
This composite part includes a coding sequence for the protein metallothionein and the protein arsenate reductase, both codon optimized for use in the Chlamydomonas reinhardtii chloroplast. The intention was for them to work synergistically to improve the uptake of arsenic out of contaminated water.
Cloning into E. coli and Verification
The constructs were designed by our team and produced by IDT. They were transformed into 10-Beta competent E. coli cells from NEB. The cloning was successful, as the positive control plate showed significantly more colonies than the negative control plate.
This was confirmed with a restriction digest of the plasmid using XbaI and BstxI. MT-ArsC was expected to have two bands of 4.4kb and 3.7kb. The number and size of bands shown in the gel were as expected, and indicated that the plasmid had been successfully integrated with our combined parts. This is a contrast to the MT-pASapI backbone, which should result in two bands of 4.4kb and 2.3kb.
Transformation into Chlamydomonas reinhardtii
We were unable to successfully transform this construct into C. reinhardtii.
