BBa_K2005002 1 BBa_K2005002 LacZ-alpha, UV-maximized 2016-10-17T11:00:00Z 2016-10-18T08:18:30Z Synthetic variant of Bba_I732006 LacZ alpha fragment with its coding DNA redesigned to maximize its susceptibility to UV-induced DNA mutation. Compared with standard LacZ, this gene is therefore more likely to mutate into diverse forms. ===Sequence Design=== To generate this artificial DNA sequence, we employed our custom-made algorithm for modifying gene sequences to introduce mutagenic sites. These sites were identified based on prior research on radiological damage, which identified dipyrimidine motifs as particularly vulnerable. These sites were identified based on prior research on DNA irradiation, where dipyrimidine motifs as particularly vulnerable. At these motifs, synonymous codon substitutions were made to make replacements for ones with higher mutation risks. In addition, our algorithm used heuristics to factor in the effect different codons have on gene expression to ensure that the gene not only produced the same protein but produced it at similar levels. Overall we could increase the predicted number of UV-mutation sites by 63% ===Assembly=== This sequence was synthesized and ligated into pSB1C3. We confirmed that this construct was synthesized and integrated correctly by sequencing. false false _2472_ 19415 19415 9 false To generate this artificial DNA sequence, we employed our custom-made algorithm for modifying gene sequences to introduce mutagenic sites.
