Part:BBa_K1129012
T7 Repeat/Spacer Region of T7 Bacteriophage
T7 Repeat/Spacer Region of Streptococcus thermophilus
This part confers resistance against T7 phage upon a strain containing the Cas9 and TracrRNA parts.
This part is computationally verified to target all of 13a, K30, T3 and T7 genomes
Short segments of foreign DNA, called spacers, are incorporated into the genome between CRISPR repeats, and serve as a 'memory' of past exposures.[6] By associating with CAS9, an enzyme with both endonuclease and DNA-binding activity, CRISPR spacers are then used to recognize and silence exogenous genetic elements in a manner similar to RNAi in eukaryotic organisms. http://en.wikipedia.org/wiki/CRISPR Sequence and Features
New application
Group: SCUT-FSE-CHINA 2017 The N20 sequence 5'-ACCAATCTGAACCACTGTGT-3‘ has been selected from BBa K1129012 to form a new sgRNA in our CRISPR system. The new sgRNA has been submitted in part BBa_K2325003 We fused crRNA and tracrRNA as a single synthetic guide RNA (sgRNA), while UBC2013 constructed crRNA (repeat-spacer array) and tracrRNA separately. In their construct, the crRNA and tracrRNA were separately transcript, followed by the combination of these transcripts to form the sgRNA. The resist efficiency may decrease when the crRNA and tracrRNA not 100% match successfully. The way we constructed the sgRNA obviated the need for processing the transcribed CRISPR array (pre-crRNA) into individual crRNA components, helping to promote the function of resistance against T7 phage.
