T7 phage N20-sgRNA

The BBa_K2325003 is a DNA sequence contains N20 associated with sgRNA. The N20 is selected from the genome of T7 phage, which is responsible for the synthesis of the DNA packaging protein during phage infection. This part confers resistance against T7 phage upon a strain containing the Cas9 and sgRNA parts.

Usage and Biology

This part can be considered as an improvement of the BBa_K1129012, as they contain same N20 sequence but different sgRNA sequence. We fused crRNA and tracrRNA as a single synthetic guide RNA (sgRNA), while UBC iGEM 2013 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.
