Enzymic activities have been measured in cell-free extracts from nitrogen-starved cultures ofAnkistrodesmus braunii. During ten hours of nitrogenstarvation the activities of the enzymes nitrite reductase (E.C.1.6.6.4), glutamic dehydrogenase (E.C.1.4.1.4), glutamine synthetase (E.C.6.3.1.2) and urea amidolyase (E.C.3.5.1.5) were derepressed while the activities of the enzymes malate dehydrogenase (E.C.1.1.1.37) and hexokinase (E.C.2.7.1.1) remained more or less unchanged. In contrast, the photosynthetic capacity of the nitrogen-starved cultures declined rapidly and accompanying this decline were losses in the activities of ribulose diphosphate carboxylase (E.C.4.1.1.39) and triose phosphate-NADP-dehydrogenase (E.C.1.2.1.13).

The distribution of nitrate and nitrite reductase, glutamic dehydrogenase, cytochrome oxidase, fumarase, peroxidase and catalase in particular fractions of barley roots, separated by differential and density gradient centrifugation, has been determined. Evidence obtained suggests that there are three separate groups of particles, one, the mitochondria, containing cytochrome oxidase, fumarase and glutamic dehydrogenase, one containing catalase, and one containing nitrate and nitrite reductase. The results show that, under certain conditions, the high osmotic pressures obtained in sucrose density gradients may cause artefacts due to the release of enzymes, especially nitrite reductase, from the particles.
