Applications of BBa_K917005

Expression of this biobrick inhibits growth of cells in the presence of nitro drugs such as metronidazole. We have rigorously tested this biobrick's potential as a counter-selectable marker in its pre-biobrick form (in Blue script vector with lac promoter).Although growth of cells containing nitroreductase is inhibited in plates, it is not absolute and therefore unsuitable for couter-selection. Aerobic liquid culture results are more promising with profound growth inhibition of nitroteductase-containing cells while control cells are growing.

Liquid aerobic cultures of BS-nitroreductase and BS-control in the presence and absence of metronidazole. At 150 ug/ml metronidazole, cells which contain nitroreductase show almost no growth. Error bars are standard error of the mean. Inital OD600 (just after inoculation) was subtracted.
