P1003 Casette with 10 Amber substitutions
P1003 Kanamycin resistance cassette with 10 serine codons in the coding sequence substituted for amber stop codons (TAG): S17Amb, S36Amb, S60Amb, S116Amb, S133Amb, S154Amb, S189Amb, S200Amb, S240Amb, S242Amb. When transformed into E .coli there is no P1003 expression and no kanamycin resistance showing that 10 amber substitutions effectively prevents expression. This part is an improvement upon BBa_K914018 (https://parts.igem.org/Part:BBa_K914018)
Figure 1. Growth curves of double transformed Top10 E. coli strains in 400 μg/mL Kanamycin.
Figure 2. Graph showing the probability of a read-through (and therefore expression) of a gene with number of amber STOP codons within the coding sequence of the gene. When there are 10 amber STOP codons in the coding sequence 1 in every 10^18 translation attempts may result in expression of the gene.
