On the induction of nitrate reductase ec 1.6.6.1 and nitrite reductase ec 1.6.6.4 in synchronized chlorella cultures






Planta (Heidelberg) 132(3): 285-290

On the induction of nitrate reductase ec 1.6.6.1 and nitrite reductase ec 1.6.6.4 in synchronized chlorella cultures

Nitrate- and nitrite-reductase (EC 1.6.6.1 and EC 1.6.6.4) activities were determined during the light-dark changes in 2 completely synchronized Chlorella strains. A sharp increase of both enzyme activities durng the 1st light hour was found in C. vulgaris F tertia, a smaller one in C. pyrenoidosa. The rise in enzyme activity could only be inhibited by actidione but not by antibiotics which inhibit plastidic protein synthesis. Light may cause a de novo synthesis of both enzymes on cytoplasmic ribosomes. It is assumed that light effects a release of substances to the cytoplasm, probably formed during CO2-fixation, which can effect a cytoplasmic protein synthesis.
