Design Notes

This sequence has been designed to target lsr2A gene in different strains such as S. ambofaciens ATCC 23877, S. bottropensis ATCC 25435, S. venezuelae ATCC 10712 and S. rimosus ATCC 10970. The part is also designed to be cloned between NcoI (CCATGG) and SnaBI (TACGTA) sites into the pCRISPR-dCas9 plasmid published by Tong and collaborators (ACS Synthetic Biology, 2015). This plasmid encodes a dead version of Cas9 that can be used to silence gene expression at specific loci. Twenty nucl. (ACCTGAACCTTCTGTGCCAC) are perfect the beginning of lsr2A gene, the following nucleotide. (GTTTTAGAGCTAGAAATAGCAAGTTAAAATAAGGCTAGTCCGTTATCAACTTGAAAAAGTGGCACCGAGTCGGTGCT) correspond to the gRNA scaffold.
