Abstract:
:Nitrate reductase of the salt-tolerant alga Dunaliella parva could utilize NADPH as well as NADH as an electron donor. The two pyridine nucleotide-dependent activities could not be separated by either ion exchange chromatography on DEAE-cellulose or gel filtration on Sepharose 4B. The NADPH-dependent activity was not inhibited by phosphatase inhibitors. NADPH was not hydrolyzed to NADH and inorganic phosphate in the course of nitrate reduction. Reduction of nitrate in vitro could be coupled to a NADPH-regenerating system of glycerol and NADP-dependent glycerol dehydrogenase. It is concluded that the nitrate reductase of D. parva will function with NADPH as well as NADH. This is a unique characteristic not common to most algae.
