Nitrite reductase (NIR; EC 1.7.7.1) is a central enzyme in nitrate assimilation and is localized in plastids. The present study concerns the regulation of the appearance of NIR in cotyledons of the mustard (Sinapis alba L.) seedling. It was shown that light exerts its positive control over the nitra

Density-labelling with deuterium oxide has been used to distinguish preexisting from newly made ascorbate oxidase (EC 1.10.3.3) molecules in cotyledons of the mustard seedling (Sinapis alba L.). The time course of the change in bandwidth of isopycnically banded enzyme, taken together with the accomp
An increase of glutathione reductase (GR; EC 1.6.4.2) activity during the transformation of mustard (Sinapis alba L.) cotyledons from storage organs to photosynthetically competent leaves was previously found to be controlled by light acting via phytochrome (Drumm, H., Mohr, H., Z. Naturforsch. 28c
