Reductive pentose phosphate cycle in Nitrosocystis oceanus.
Campbell, Ann E. (Woods Hole Oceanographic Institution, Woods Hole, Mass.), Johan A. Hellebust, and Stanley W. Watson. Reductive pentose phosphate cycle in Nitrosocystis oceanus. J. Bacteriol. 91:1178-1185. 1966.-Assays in cell-free extracts of Nitrosocystis oceanus, a marine chemoautotrophic bacterium, have demonstrated the presence of all of the enzymes of the reductive pentose phosphate cycl...
متن کاملEvidence for the participation of the reductive pentose phosphate cycle in photoreduction and the oxyhydrogen reaction.
The assimilation of (14)C-sodium bicarbonate has been measured in Scenedesmus obliquus as 1) photosynthesis, 2) photoreduction (light dependent incorporation of carbon dioxide by hydrogen adapted cells under conditions where photosynthesis is inoperative), and 3) the oxyhydrogen reaction (dark assimilation of carbon dioxide by hydrogen adapted cells in an atmosphere of hydrogen and 1% oxygen). ...
متن کاملInfluence of Light Intensity on Reductive Pentose Phosphate Cycle Activity during Photoheterotrophic Growth of Rhodospirillum rubrum.
Light intensity during growth affects the proportion of carbon dioxide fixed by the reductive pentose phosphate cycle relative to that incorporated via C(4) acids in acetate phototrophs of Rhodospirillum rubrum. With cells grown at high light intensity (9000 lux) the specific activities of ribulose-1, 5-diphosphate and propionyl CoA carboxylases were increased compared with cells grown at low l...
متن کاملPhotosynthesis in Rhodospirillum rubrum. 3. Metabolic control of reductive pentose phosphate and tricarboxylic acid cycle enzymes.
Enzymes of the reductive pentose phosphate cycle including ribulose-diphosphate carboxylase, ribulose-5-phosphate kinase, ribose-5-phosphate isomerase, aldolase, glyceraldehyde-3-phosphate dehydrogenase and alkaline fructose-1,6-diphos-phatase were shown to be present in autotrophically grown Rhodospirillum rubrum. Enzyme levels were measured in this organism grown photo- and dark heterotrophic...
متن کاملThe reductive pentose phosphate cycle. III. Enzyme activities in cell-free extracts of photosynthetic organisms.
The reductive pentose phosphate cycle (6, 29, 8) is currently believed to be the pathway by which CO2 is converted to carbohydrate in photosynthesis. Evidence for the functional role of this cycle is derived mainly from isotope experiments. Brief exposure of photosynthesizing algae to C1409 produces radioactive 3-phosphoglycerate (3-PGA ) 3, labelled mainly in the carboxyl group ( 11 ). The cyc...
