NsrR
NsrR - Nitric oxide sensitive PyeaR repressor protein
Biology of NsrR
Escherichia coli (E. coli) detects environmental nitrate by the yeaR-yoaG operon. According to Figure 1, PyeaR (Lin, et al., 2007) is regulated by the Nar two-component regulatory system (Nohno et al., 1989; Li et al., 1987) and NsrR nitric oxide sensitive repressor protein (Partridge et al., 2009). When there is nitrate or nitrite, the repression from the Nar system on PyeaR will be relieved due to the binding between the two. On the other hand, some nitrate will be converted into nitric oxide by nitrate reductase. Nitric oxide will bind to the NsrR protein and relieve the repression on PyeaR. As a result, any genes that are downstream of PyeaR will be expressed.
