The Photoassimilation of Succinate to Hexose by Rhodospirillum Rubrum.
1. A pathway for the synthesis of hexose from succinate by Rhodospirillum rubrum is proposed. 2. With 2,3-(14)C(2)-labelled succinate and fumarate as substrates in experiments with chromatophores and a soluble enzyme fraction of R. rubrum it was found that the products of succinate metabolism by the extracts were the same as in whole cells. It was also found that the light-dependent oxidation o...
متن کاملThe Photo-oxidation of Succinate by Chromatophores of Rhodospirillum Rubrum.
1. The stoicheiometry of the photo-oxidation of succinate by chromatophores has been investigated with [2,3-(14)C(2)]succinate. It was found that there is a stoicheiometric relationship between the amount of succinate oxidized and the NAD reduced, and that fumarate is the only product of succinate oxidation. 2. The possibility of a direct hydrogen transfer from succinate to NAD in this reaction...
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 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...
