The terminal oxidation system of Azotobacter vinelandii.
Preliminary work showed that Azotobacter vinelandii strain 0 (A2otobacter agile var. vinelandii) yielded a more stable enzyme extract than any other species tried, and this organism was used throughout. Repaske (1954) and Alexander and Wilson (1954) have reported the essential details for growing and harvesting the culture and for making the enzyme preparations. The succinic dehydrogenase (SD) ...
متن کاملMetapyrogatechase: Catechol Oxidation in Azotobacter Vinelandii
Benzoic acid metabolism was studied in Azotobacter vinelandii. 14 A radioactive intermediate of C-benzoic acid metabolism was discovered. Preliminary evidence suggests that this intermediate may be 2 ,-hydroxybenzoate but positive identification was not achieved, values for several hydroxybenzoates and catechol on paper chromato graphy in various solvent systems are given. The oxygenase, metap...
متن کاملPlasmids of Azotobacter vinelandii.
Four laboratory strains and two isolates of Azotobacter vinelandii were found to contain plasmids. Twenty-five laboratory strains which could fix nitrogen did not have free, covalently closed circular plasmid DNA. The plasmids varied in size from 9 to 52 megadaltons, and each strain yielded only one plasmid. No discernible differences in ability to fix nitrogen were found between plasmid-bearin...
متن کاملUltrastructure of Azotobacter vinelandii.
Vegetative cells and cysts of Azotobacter vinelandii 12837 were prepared for electron microscopy by several methods assumed to preserve structural details destroyed by techniques previously reported in the literature. Examination of large numbers of cells and cysts by these methods revealed four structural details not reported previously: intine fibrils, intine vesicles, intine membrane, and mi...
متن کاملGenes in Azotobacter vinelandii
Azotobacter vinelandii contains a heterodimeric, membrane-bound [NiFelhydrogenase capable of catalyzing the reversible oxidation of H2. The 13 and at subunits of the enzyme are encoded by the structural genes hoxK and hoxG, respectively, which appear to form part of an operon that contains at least one further potential gene (open reading frame 3 1ORF3]). In this study, determination of the nuc...
