PlacI-B0034-NiR cluster

This composite part is composed of R0010, B0034 and K2275001 which encodes nitrite reductase derived from E. coli K-12 MG1655 strain. Then we used Griess reagent assay to test the activity of NiR. The principle and mechanism of Griess reaction are shown below.

The mechanism of griess reaction

When the broth contains nitrite, by adding the Griess reactant which consists of naphthylethylenediamine dihydrochloride, sulphanilamide, phosphoric acid can form a diazonium salt with nitrite. The diazonium salt will have absorbance at wavelength 545 nm. By the reaction, we can further calculate the nitrate conversion.
