arsC-IEE5-fTNa

Background

This composite part includes a coding sequence for the protein arsenate reductase and the protein ferritin, 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.

Figure 1. The plate on the left is the experimental transformation of the part into plasmid backbone MT-pASapI using Golden Gate Assembly. Multiple individual colonies are present on the plate, indicating successful transformation. The plate on the right is the negative control. The colonies present may indicate a high background or low efficacy of our initial digest with SapI.

This was confirmed with a restriction digest of the plasmid using XbaI and BstxI. ArsC-FtnA 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 in the middle two wells, 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.
