Prosthetic Groups and Mechanism of Action of Nitrate Reductase from Neurospora Crassa

摘要: Publisher Summary The assimilation of nitrate by higher plants, fungi, algae, and microorganisms as well the use a terminal respiratory oxidant in absence oxygen require presence reductase, which catalyzes two electron reduction to nitrite. ubiquity importance this reaction, ease assaying product nitrite, has resulted growing literature on many aspects enzymology regulation reductase. assimilatory enzyme from mold Neurospora crassa been intensively studied. This chapter discusses study present an evaluation types prosthetic groups enzyme. Workers studying reductase tissues plants have also observed destructive proteolytic activities during extraction Nitrate is energetically wasteful rapidly repressed ammonia. Thus hypothesis that inducible enzymes type may be so constructed especially susceptible specific intracellular inactivation, reasonable its logic.
