Part:BBa_K1499253
aeBlue generator with 3 UAG stops + supP tRNA
This part encodes uvsE, a putative UV damage endonuclease found in D. radiodurans that protects cells from radiation-induced DNA damage.
Usage and Biology
The design of the protein coding region of this part was based off Team Uppsala's 2012 chromoproteins kit, specifically BBa_K864401. Please see this parts page for the biology of this protein. The supP tRNA is from Stanford-Brown-Spelman's 2014 Amberless toolkit, or BBa_K1499251. Together, this generator was used to test the orthogonality of the UAG->Leucine coding (Figure 1).
We have observed that this generator works in amberless E. coli, but not DH5-alpha. Because of the toxicity of the tRNA, the part will be difficult to transform into any strain of bacterium that contains genes with the amber stop codon.

Characterization
Verification of Part
The part was sequence verified in the pSB1C3 backbone before submission to the registry. Two reads, forward and reverse, were obtained using VF2 and VR (Figure 2).
Results
The part has been confirmed to work as expected (Figure 3).
