Design Notes

The RBS before cysPUWA was designed using the Salis Lab RBS Designer [1]. The pre-sequence used was the PgntK promoter sequence, and the protein-coding sequence used was the cysP sequence. This particular RBS was chosen (see Figure 1 below) because it had the highest translation rate.

See the registry pages for negative feedback membrane stress promoter PgntK (BBa_K2194002), cysPUWA proteins (BBa_K2194003), Elowitz RBS (BBa_B0034), and sulfate binding protein sbp (BBa_K2194001) sources.

The RBS before cysPUWA has the synthetic sequence 5’AAGCGGACGACACACAAGGCTCCACCAAA3’ and was designed with the “Salis Lab RBS Designer” [1].

The terminator “L3S3P21” after sbp has the synthetic sequence 5’CCAATTATTGAAGGCCTCCCTAACGGGGGGCCTTTTTTTGTTTCTGGTCTGCC3’. It is sourced from Chen et al [2] and is notable because it is a strong, recombination-resistant terminator.
