Nitrate reductase light

Diurnal variation of nitrate reductase activity was first observed many years ago (Hageman et al., 1961), and was shown to be maintained for several days in continuous light, but to disappear during continuous dark-...

The uptake of nitrate and subsequent conversion to reduced nitrogen in cells requires a change of five in the oxidation state and proceeds in a stepwise fashion. The initial reduction takes place via the nitrate/nitrite reductase enzyme present in phytoplankton and requires large amounts of the reduced nicotinamide-adenine dinucleotide phosphate (NADPH) and of adenosine triphosphate (ATP) and thus of harvested light energy from photosystem II. Both the nitrogenase enzyme and the nitrate reductase enzyme require iron as a cofactor and are thus sensitive to iron availability. 

Irradiation of the pure protein in an open system, as well as in anaerobic atmosphere.This experiment was performed on regarding the blue-light activation of nitrate reductase from several sources (2).
