1.7.1.1 | light |
enzyme is posttranslationally activated by light. Light also has a positive effect also on de novo synthesis of nitrate reductase. Daily variations in nitrate reductase activity are mainly caused by post-translational modifications. As for angiosperms, the post-translational light activation is inhibited by 3-(3,4-dichlorophenyl)-1,1-dimethylurea, an inhibitor of photosynthesis and stomata opening |
