We recently showed that cassette integration and deletion in integron platforms were occurring through unconventional site-specific recombination reactions involving only the bottom strand of attC sites. The lack of sequence conservation among attC sites led us to hypothesize that sequence-independent structural recognition determinants must exist within attC sites. The structural dat... https://www.lightemupsequences.com/limited-save-Custom-Congratulations-Banner-p4839-hot-choice/
