pRecA

Protein RecA allows for homologous recombination and is essential in the repair and maintenance of E.coli DNA. It has been shown that RecA is upregulated in E.coli after administration of known carcinogenic agent MNNG. (Norman et al, 2004)


Usage and Biology

iGEM Leiden 2018 has created a screening system for the detection of new antibiotics. We have tested several stress-activated promoters against a repertoire of known antibiotics (Figure 1) using flow cytometry. We fused promoters to green fluorescent protein and stressed transformed DH5a cells for several hours.

As can be observed in Figure 1 the RecA promoter is severely downregulated by multiple antibiotics.
