The terminal oxidases of Azotobacter vinelandii
Biochemical and Biophysical Research Communications, 1973Abstract The terminal respiratory chain of the aerobic nitrogen-fixing bacterium Azotobacter vinelandii was investigated by photochemical action spectra. Terminal cytochrome oxidases a 2 , a 1 and o were confirmed as being the terminal oxidases for the physiological substrates NADH and L-malate.

Metabolism of methylammonium by Azotobacter vinelandii [PDF]
Archives of Microbiology, 1984 Azotobacter vinelandii takes up the ammonium analog methylammonium from the external medium and metabolizes it to a less polar compound which has been identified as N-methylglutamine. The enzyme glutamine synthetase appears responsible for methylammonium metabolism in this organism and full activity of the enzyme is required for maximal rates of ...

Oxidative phosphorylation in Azotobacter vinelandii
Biochimica et Biophysica Acta, 1959Abstract 1. 1. An extract of Azotobacter vinelandii was fractionated and oxidative phosphorylation studied with a small-particle fraction. 2. 2. The phosphorylating system in the particles was inactivated by suspension in dilute salt solutions. This inactivation could be partly reversed by raising the salt concentration. Bivalent cations were

β-Ketothiolase genes in Azotobacter vinelandii
Gene, 2000Azotobacter vinelandii is proposed to contain a single beta-ketothiolase activity participating in the formation of acetoacetyl-CoA, a precursor for poly-beta-hydroxybutyrate (PHB) synthesis, and in beta-oxidation (Manchak, J., Page, W.J., 1994. Control of polyhydroxyalkanoate synthesis in Azotobacter vinelandii strain UWD.

Determination of the size of the Azotobacter vinelandii chromosome
Molecular and General Genetics MGG, 1993The chromosome of Azotobacter vinelandii UW was digested separately with the rape cutter restriction endonucleases SwaI (5'-ATTTAAAT), PmeI (5'GTTTAAAC) and PacI (5'-TTAATTAA) and the products were separated by pulsed-field gel electrophoresis. The size of the chromosome was determined to be approximately 4.5 megabase pairs (Mb) based on the sum of the

A chromosomal linkage map of Azotobacter vinelandii
Molecular and General Genetics MGG, 1990A chromosomal map of Azotobacter vinelandii strain UW was constructed. The map was based on measures of cotransfer of various markers mediated by plasmids R68.45 and pJB3JI, on results obtained from conjugal experiments with R-primes, and on recombinants obtained by chromosomal transfer mediated by RP4/Tn5-Mob.

Tungstate as an antagonist of molybdate in Azotobacter vinelandii
Archives of Biochemistry and Biophysics, 1957Abstract 1. 1. Tungsten has been shown to be a competitive inhibitor of the molybdenum functions of Azotobacter vinelandii. 2. 2. The uptake of molybdenum by Azotobacter vinelandii is more sensitive to tungsten inhibition than is growth. 3. 3. Vanadium does not overcome tungsten inhibition.

Alginate Production byAzotobacter Vinelandii
Critical Reviews in Biotechnology, 1997Although all commercial alginates are today of algal origin, there is interest in the production of alginate-like polymers from bacteria. The species Azotobacter vinelandii seems to be the best candidate for the industrial production of alginate molecules characterized by a chemical composition, molecular mass and molecular mass distribution suited to ...

Dimerization of Azotobacter vinelandii flavodoxin (azotoflavin)
Archives of Biochemistry and Biophysics, 1975Abstract Molecular weight determinations by gel filtration of Azotobacter vinelandii flavodoxin (azotoflavin) which had been stored aerobically for various periods of time indicated that this flavoprotein electron carrier could exist in the monomeric ( M r = 23,000) or dimeric ( M r = 46,000) form.
