pYMB (BBa_K624004) is described to contain the ori (origin of replication), rep gene (required for replication) of pMGT. Once the synthetic work had been done, pYMB is constructed by equipping the ori, the appropriate promoter for AMB-1 (Pmms16 and Pmsp3 as our candidate) and rep gene on the commercial plasmid pUG19 which was revised as the expression of Biobrick backbone pSB1A1 with promoter Pmsp1. The constructed vector is capable of replicating within both E. coli and AMB-1, fully sufficing a competent shuttle vector for genetic engineering the magnetotactic bateria.

Listeriolysin O (LLO) is a hemolysin produced by the bacterium Listeria monocytogenes, a pathogen that is responsible for listeriosis. LLO is activated within phagosomes of cells that have phagocytosed L. monocytogenes cells, and lyses the membrane of phagosome. The bacteria is then able to escape into the cytosol without damaging the plasma membrane, and grow intracellularly. This would result in the protection from extracellular immune system.

Invasin is an outer membrane protein that allows bacteria to penetrate mammalian cells. It is from Yersinia enterocolitica. Invasin binds to multiple Beta 1 chain integrin receptors on mammalian cells with high affinity, which induces endocytosis and internalization.

All of the ribosome binding sites are from Pmsp3, the strongest promoter of AMB-1.(BBa_K624012)
