P + RBS + ftsZ + RBS + GFP + Term
This biobrick enables the complete production of ftsZ and GFP (as an indicator of production). The same RBS is used upstream of both ftsZ and GFP in order to approximate a 1:1 production, so that the flourescent intensity will give a relative indication of ftsZ production.
As this picture below illustrates, under normal WT conditions, FtsZ will form the Z ring at the middle of the cell. When overexpressed, FtsZ will polymerize non specifically at the polar ends of the cell, thereby cleaving the cell to form a minicell.
