Glycolate pathway in algae.
No glycolate oxidase activity could be detected by manometric, isotopic, or spectrophotometric techniques in cell extracts from 5 strains of algae grown in the light with CO(2). However, NADH:glyoxylate reductase, phosphoglycolate phosphatase and isocitrate dehydrogenase were detected in the cell extracts. The serine formed by Chlorella or Chlamydomonas after 12 seconds of photosynthetic (14)CO...
متن کاملGlycolate oxidase activity in algae.
The g1lycolate oxidase reactioni by x-hich gly colate is oxidized to glyoxylate (3, 10) is catailyzed by a flavoprotein (18) th,at is widely distributed in higher plants (12) and fungi (4). Its presence is g,elleralllly assumed in all phoiosynithetic tissuies, since glycolate is an early product of photosynthesis (14), yet this substrate is tusually found in oiily minute amounits. The oxidation...
متن کاملRespiration in blue-green algae.
The low rate of endogenous respiration exhibited by the blue-green algae Anacystis nidulans and Phormidium luridum was not increased by the addition of respiratory substrates. However, endogenous respiration was inhibited by low concentrations of cyanide and by high carbon monoxide tensions. In addition, the uncouplers dinitrophenol and carbonyl cyanide p-trifluoromethoxyphenylhydrazone both st...
متن کاملPteridines in blue green algae.
The presence of a remarkably high concentration of pteridiineS in the blue green alga, Anacystis nidulanis 5, wvas demonstrated by Forrest, van Baalen, and Myers in 1957 (2). A number of (lifferent pteridines were then isolated and ideentifie(l. These included 2-amino-4-hydroxypteridine, 2,6-diamino-4-hydroxypteridline (10), a yellow pteridine assigned the structure 2-aimino-4-hydroxv-6-propion...
متن کاملIntracellular localization of glycolate dehydrogenase in a blue-green alga.
Glycolate dehydrogenase activity was detected in cell-free extracts of Oscillatoria sp. prepared by osmotic lysis of spheroplasts in 0.05 m potassium phosphate buffer, pH 7.5, containing 0.3 m mannitol. Most of the enzyme activity was found in a particulate fraction and localized in the photosynthetic lamellae after centrifugation in a discontinuous sucrose density gradient. Enzyme activity was...
