Azotobacter vinelandii Citrate Synthase

Biochemistry, 1995
We have purified the citrate synthase from Azotobacter vinelandii and have determined that the size of the subunit is 48,000 Da and the structure of the holoenzyme is a hexamer. This contrasts with earlier estimates that indicate a 58,000 Da subunit and a tetrameric structure.

Acid Production by Azotobacter vinelandii

Nature, 1963
Azotobacter vinelandii has been characterized by its lack of acid production in culture1. In fact, most species of Azotobacter do not form acid, but appear to oxidize carbohydrates completely to carbon dioxide and water2. The notable exceptions to this are the acid-tolerant A. indicum (Beijerinckia indica)3 and A. macrocytogenes4 that are characterized

The replication origin of Azotobacter vinelandii

Molecular and General Genetics MGG, 2000
The putative replication origin of Azotobacter vinelandii was cloned as an autonomously replicating fragment after ligation to an antibiotic resistance cartridge. The resulting plasmids could be isolated and labelled by Southern hybridisation with the antibiotic resistance cartridge as probe and also visualised by electron microscopy.

Electron transport in Azotobacter vinelandii

Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1966
Summary 1. The nature and intracellular distribution of the respiratory enzyme system of Azotobacter vinelandii has been investigated. 2. Whole cells of this organism were found to contain high concentrations of ubiquinone (Q-8) but, in contrast to Azotobacter vinelandii strain O, no menaquinone (vitamin K2) was detected. 3.

Silicate in the Metabolism of Azotobacter vinelandii

Nature, 1958
MOLYBDENUM complexed as silico-molybdate has been shown to be very active in the re-activation of aldehyde oxidase from which the molybdenum has been removed by dialysis1. Other reports have implicated silicate, phosphate and other anions as agents which increase the activity of molybdate -dependent enzymes2,3.

Oxidative phosphorylation in Azotobacter vinelandii

Biochimica et Biophysica Acta, 1959
Abstract 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

The cytochrome system of Azotobacter vinelandii

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1967
1. Difference spectra and carbon monoxide action spectra of Azotobacter vinelandii small particles indicate the presence of cytochromes c4 + c5, b1, a1, a2 and o, of which a1, a2 and possibly o may be acting as terminal oxidases. 2. The aerobic steady-state reduction of cytochrome b1 was unexpectedly found to be much lower than that of cytochromes ...

The terminal oxidases of Azotobacter vinelandii

Biochemical and Biophysical Research Communications, 1973
Abstract 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.

Glucose catabolism in Azotobacter vinelandii

Archives of Biochemistry and Biophysics, 1964
Abstract The catabolism of glucose in proliferating cells of Azotobacter vinelandii has been examined with respect to the nature and participation of individual pathways. The radiorespirometric method and substrate incorporation studies were used in this investigation.

Tn 10 mutagenesis in Azotobacter vinelandii

Molecular and General Genetics MGG, 1987
The tetracycline-resistant transposon Tn10 and its "high-hopper" derivative Tn10HH104 were introduced into the Azotobacter vinelandii genome using suicide conjugative plasmids derived from pRK2013. Several types of mutants induced by either of these elements are described.
