<h5>Note</h5>

<p>Note that parts must be documented on the <a href="http://parts.igem.org/Main_Page"> Registry</a>. This page serves to <i>showcase</i> the parts you have made. Future teams and other users and are much more likely to find parts by looking in the Registry than by looking at your team wiki.</p>

<p>You can add parts to the Registry at our <a href="http://parts.igem.org/Add_a_Part_to_the_Registry">Add a Part to the Registry</a> link.</p>
+
<p>We encourage teams to start completing documentation for their parts on the Registry as soon as you have it available. The sooner you put up your parts, the better you will remember all the details about your parts. Remember, you don't need to send us the DNA sample before you create an entry for a part on the Registry. (However, you <b>do</b> need to send us the DNA sample before the Jamboree. If you don't send us a DNA sample of a part, that part will not be eligible for awards and medal criteria.)</p>

PhagED: a molecular toolkit to re-sensitise ESKAPE pathogens

Parts

This year the iGEM Edinburgh_OG team focused on developing a modular toolkit using CRISPR systems and phages to re-sensitise antibiotic-resistant bacteria. As a BioBrick we submit the E. coli codon-optimised Staphylococcus aureus Cas9.

How does this part work?

  • Our SaCas9 can be programmed to cleave specific target sequence followed by the PAM sequence (5’-NNGRRT-3’).
  • To express SaCas9, it requires suitable machinery such as promoter, RBS,and terminator.
  • To programme SaCas9, you need to design guide RNA (tracrRNA [2], 21 bp spacer flanked by direct repeats [2] ).




Advantages of SaCas9 compared with the conventional Streptococcus pyogenes Cas9:

  • Smaller size (1053 amino acids against 1368) resulting in an easier expression/delivery
  • Different PAM sequence recognised (5’-NNGRRT-3’ ) increasing the usability
  • Higher efficiency of SaCas9 over SpCas9 [2]
