Properties of a Protein Activator of NAD Kinase from Plants.
Purification of pea (Pisum sativum) seedling NAD kinase by DEAE-cellulose column chromatography resulted in loss of activity, due to dissociation of an activator from the enzyme. The purified enzyme preparation, which was almost completely inactive, regained the activity when the activator was added back.The activator was purified 320-fold by ion exchange chromatographies. The activator was sus...
متن کاملBlue light activates a specific protein kinase in higher plants.
Blue light mediates the phosphorylation of a membrane protein in seedlings from several plant species. When crude microsomal membrane proteins from dark-grown pea (Pisum sativum L.), sunflower (Helianthus annuus L.), zucchini (Cucurbita pepo L.), Arabidopsis (Arabidopsis thaliana L.), or tomato (Lycopersicon esculentum L.) stem segments, or from maize (Zea mays L.), barley (Hordeum vulgare L.),...
متن کاملProline metabolism and NAD kinase activity in greenbean plants subjected to cold-shock.
The aim of the present work was to examine the relationship between proline metabolism and NAD kinase activity in greenbeans submitted to cold-shock. For this, 15-day-old greenbean plants were subjected to a temperature of 4 degrees C (cold shock) for 180 min. Our results indicate that the plants showed foliar accumulation of proline, with the enzymes ornithine-delta-aminotransferase (OAT) and ...

متن کاملSelenium in Higher Plants.
Plants vary considerably in their physiological response to selenium (Se). Some plant species growing on seleniferous soils are Se tolerant and accumulate very high concentrations of Se (Se accumulators), but most plants are Se nonaccumulators and are Se-sensitive. This review summarizes knowledge of the physiology and biochemistry of both types of plants, particularly with regard to Se uptake ...
