additional information
-
the enzyme is stimulated on the addition of flavin or quinone compounds. Supplementation of the azoreductase assay with redox active substances (riboflavin, anthraquinone-2,6-disulfonic acid, and anthraquinone-2-sulfonic acid) increases the specific activity of membrane-bound azoreductase as the shuttling of electrons to azo substrate is promoted
