Isolation and Purification of the Intracytoplasmic Membranes of Rhodospirillum Rubrum.
Holt, Stanley C. (University of California, Davis), and Allen G. Marr. Isolation and purification of the intracytoplasmic membranes of Rhodospirillum rubrum. J. Bacteriol. 89:1413-1420. 1965.-When Rhodospirillum rubrum was disrupted in a French pressure cell, two colored bands were observed after density-gradient centrifugation: an upper band containing chromatophores and a lower band containin...
متن کاملDevelopment and growth of photosynthetic membranes of Rhodospirillum rubrum.
In cell-free extracts from low-aeration suspensions of Rhodospirillum rubrum strain G-9, bacteriochlorophyll a was distributed in two bands after rate-zone sedimentation in sucrose density gradients. From the physicochemical properties of these fractions, it was concluded that the upper band consisted of small membrane fragments, whereas the major band was composed of fragmented vesicular intra...
متن کاملThe Structure of Rhodospirillum rubrum
Cells from serial cultures of R. rubrum, grown anaerobically in the light, were harvested at intervals from (1/2) to 15 days and sectioned for electron microscopy by conventional methods. Cells of this species possess a multilayered outer envelope, and the external cell surface is differentiated into ridges extending parallel or obliquely to the long axis of the cell. Cells from very young cult...
متن کاملEffect of Light Intensity on the Formation of Intracytoplasmic Membrane in Rhodospirillum Rubrum.
Holt, Stanley C. (University of California, Davis), and Allen G. Marr. Effect of light intensity on the formation of intracytoplasmic membrane in Rhodospirillum rubrum. J. Bacteriol. 89:1421-1429. 1965.-Cells of Rhodospirillum rubrum grown at low light intensity were found to contain much more internal membrane than cells grown at high light intensity. Highly purified membranes (chromatophores)...
متن کاملPhotosynthesis in Rhodospirillum rubrum
Ribulose 1,5-diphosphate carboxylase has been isolated from autotrophically cultured Rhoclospirillum rubrum. The molecular weight is 120,000. The K, for ribulose 1,5diphosphate is 83 mM, and for CO2 is 59 mM. The enzyme is inhibited by three important metabolites: citrate, an intermediate of the tricarboxylic acid cycle; inorganic phosphate; and 3-phosphoglyceric acid, the product of the reacti...
