iGEM Toolkits: Parts Submitted


iGEM toolkits: submitted a total twenty-two parts to the registry:

  • 10 magnetosome gene groups from mamAB operon
  • 3 superassemblies of mamAB operon from set of 10
  • 2 sfGFP-mam gene fusions
  • 5 pGA (Gibson Assembly) vectors

Magnetosome Toolkit Favorite Parts

BBa_K590015 sfGFP_mamK_pGA1C3

This part consists of mamK gene from Magnetospirillum magneticum strain AMB-1, sfGFP in the backbone of pGA1C3. mamK was previously reported for its importance proper magnetosome chain organization in magnetic bacteria; it is bacterial actin-like cytoskeleton protein required for proper alignment of the magnetosomes in a chain.

BBa_K590016 sfGFP_mamI_pGA1C3

This part consists of mamI gene from Magnetospirillum magneticum strain AMB-1, sfGFP in the backbone of pGA1C3. MamI is a membrane-localized protein that localizes magnetic vesicles to the surface of cells, thus forming characteristic magnetosome chains.

The Gibson Assembly Toolkit

BBa_K590010 pGA1A3_pLacGFP

This is a high copy plasmid backbone which has ampicillin resistance, with pLac promoter and GFP.

BBa_K590011 pGA1C3_pLacGFP

This is a high copy plasmid backbone which has chloramphenicol resistance, with pLac promoter and GFP.

BBa_K590012 pGA4C5_pLacGFP

This is a low copy plasmid backbone which has chloramphenicol resistance, with pLac promoter and GFP.

BBa_K590013 pGA4A5_pLacGFP

This is a low copy plasmid backbone which has ampicillin resistance, with pLac promoter and GFP .

BBa_K590014 pGA3K3_pLacGFP

This is a medium copy plasmid backbone which has kanamycin resistance, with pLac promoter and GFP.
