LITERATURE
metabolism
-
catalytic voltammetry of enzyme variants on a modified Au electrode with the electrochemically reduced forms of benzyl viologen and anthraquinone sulfonate as artificial electron donors. The biopolymer chitosan entraps nitrate reductase on the electrode noncovalently. Both an enzyme form lacking the FAD cofactor and one lacking both the FAD and heme cofactors show catalytic nitrate reductase activity, removal of the heme cofactor results in a more significant effect on the rate of nitrate reduction
