This part consists of the <i>mamK</i> gene from <i>Magnetospirillum magneticum</i> strain AMB-1, fused to superfolder <i>gfp</i> on pGA1C3. MamK has been reported to be essential for proper magnetosome formation in magnetotactic bacteria; its bacterial actin-like cytoskeleton protein is required for proper alignment of the magnetosomes in a chain. Beyond magnetosome alignment, the MamK filament could act as a scaffold for protein localization or to alter cell morphology.

This part consists of the <i>mamI</i> gene from <i>Magnetospirillum magneticum</i> strain AMB-1, fused to  superfolder <i>gfp</i> on pGA1C3.

Since it localizes to the membrane, MamI may be useful in maximizing the flux of biosynthetic pathways as a membrane-linker protein.

This is a low copy plasmid backbone (replication origin pSC101) that confers ampicillin resistance. It has an insert with a LacI-repressible promoter driving GFP expression. It is identical to pSB4A5 except for its bglBrick prefix and suffix, and is optimized for Gibson Assembly. It is also notable that though we searched in multiple BioBrick distributions from different years, we could not find any that could be sequence-verified as pSB4A5 (the Vf2 sequence reads all suggested pSB1A2). We then generated pGA4A5 from pGA4C5 using the ampicillin cassette from pSB1A3.
