Description
Screening techniques available presently are all negatively related. The disadvantages of antibiotics are:
1. Principle of Negative Selection
2. Transformants carry a small but unnecessary risk of horizontal gene transfer to environmental microbes
3. Metabolic burden on the cells that significantly reduces the production of the desired protein
Therefore, a novel selectable marker is needed which confers metabolic ???advantage??? to the transformants.
This plasmid carries the gene proteorhodopsin.
Notes
The reading frame had to be maintained.

Source : pSB1C3 is modified. Proteorhodopsin replaces the antibiotic gene.
