As part of our studies on the physiological and ecological function of caffeine, we investigated the effect of exogenously supplied caffeine on purine, pyrimidine and pyridine metabolism in rice seedlings. We examined the effect of 1 mM caffeine on the in situ metabolism of 14C-labelled adenine,
Inosine diphosphatase bound to Golgi membranes was studied in rice (Oryza sativa L. cv Nipponkai) cells. The enzyme was solubilized with Triton X-100 from isolated rice Golgi membranes and was highly purified employing a series of chromatography steps in the presence of 20% glycerol and 0.1% Triton
The major acid phosphatase (EC 3.1.3.2) associated with aleurone particles of rice grains (Oryza sativa L. Japonica cv. Koshihikari) was purified to homogeneous state by polyacrylamide gel electrophoresis. Its molecular weight was 72,000 when determined by gel filtration and 68,000 when found by
Nucleoside degradation and salvage are important metabolic pathways but hardly understood in plants. Recent work on human pathogenic protozoans like Leishmania and Trypanosoma substantiates an essential function of nucleosidase activity. Plant nucleosidases are related to those from protozoans and
