Inhibition of Azotobacter vinelandii rhodanese by NO-donors

Biochemical and Biophysical Research Communications, 2003
Nitric oxide (NO) is a versatile regulatory molecule that affects enzymatic activity through chemical modification of reactive amino acid residues (e.g., Cys and Tyr) and by binding to metal centers. In the present study, the inhibitory effect of the NO-donors S-nitroso-glutathione (GSNO), (+/-)E-4-ethyl-2-[E-hydroxyimino]-5-nitro-3-hexenamide (NOR-3),

A chromosomal linkage map of Azotobacter vinelandii

Molecular and General Genetics MGG, 1990
A 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.

Overexpression of Ferredoxin I in Azotobacter vinelandii

Protein Expression and Purification, 1994
Azotobacter vinelandii has recently been used for a variety of genetic experiments which take advantage of its facile transformation system and its high-frequency homologous recombination. One gene that has been cloned and sequenced is the fdxA gene that encodes a small Fe-S protein called A. vinelandii ferredoxin I (AvFdI).

β-Ketothiolase genes in Azotobacter vinelandii

Gene, 2000
Azotobacter 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.

The respiratory enzyme systems of Azotobacter vinelandii

Biochimica et Biophysica Acta, 1957
Abstract 1. 1. An extract from Azotobacter vinelandii was fractionated by centrifugation into a large particle fraction (WLP) and a small particle fraction (WSP), isolated respectively in a field of 22,000 g for 30 min and 145,000 g for 60–120 min, and the supernatant (S2) from the latter centrifugation. 2. 2.

Tungstate as an antagonist of molybdate in Azotobacter vinelandii

Archives of Biochemistry and Biophysics, 1957
Abstract 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.

Dimerization of Azotobacter vinelandii flavodoxin (azotoflavin)

Archives of Biochemistry and Biophysics, 1975
Abstract 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.

Alginate Production byAzotobacter Vinelandii

Critical Reviews in Biotechnology, 1997
Although 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 ...

A Function for the Extracellular Polysaccharide of Azotobacter vinelandii

Nature, 1959
RECENT studies on the nitrogen-fixing pseudomonads and their polysaccharides1,2 have refocused attention on the function of these extra-cellular products. Beijerinck3 observed the disappearance of a mucus produced by Bacillus polymyxa, and recently the pseudomonads have been shown to degrade their extra-cellular polysaccharide4, making it plausible ...
