The rhodanese RhdA helps Azotobacter vinelandii in maintaining cellular redox balance [PDF]

open access: yes, 2010
The tandem domain rhodanese-homology protein RhdA of Azotobacter vinelandii shows an active-site loop structure that confers structural peculiarity in the environment of its catalytic cysteine residue.

THE OXALACETATE DECARBOXYLASE OF AZOTOBACTER VINELANDII

open access: yesJournal of Biological Chemistry, 1949
In 1941 Krampitz and Werkman (1) discovered an enzyme in Micro- coccus lysodeikticus which catalyzed the decarboxylation of oxalacetate. By means of an exchange reaction they were able to demonstrate the in- corporation of isotopic carbon dioxide into the p-carboxyl group of oxal- acetic acid in the presence of this enzyme (2). Similar results were ob-

Morphogenesis of Cysts in Azotobacter vinelandii [PDF]

open access: yesJournal of Bacteriology, 1970
Cultures of Azotobacter vinelandii were induced to encystment with β-hydroxybutyrate. The morphological events in the transition from cell to cyst were observed by electron microscopy of thin sections. Upon induction of encystment, cells became rounded and nonmotile.

Plasmid Transformation of Azotobacter vinelandii OP [PDF]

open access: yesMicrobiology, 1987
Azotobacter vinelandii OP which had been naturally induced to competence by growth in iron- and molybdenum-limited medium was transformed with the broad-host-range cloning vector pKT210. However, the transformation frequency at nearly saturating levels of DNA was 1000-fold lower for pKT210 than for a single chromosomal DNA marker (nif+).

The role of alginate in Azotobacter vinelandii aggregation in submerged culture Papel del alginato en la agregación de Azotobacter vinelandii en cultivo sumergido

open access: yesRevista Colombiana de Biotecnología, 2008
The culture of strain LA21, a non-mucoid strain of Azotobacter vinelandii derivative of ATCC 9046, revealed that alginate is not necessary for aggregate formation.

Identification of Regulatory Genes and Metabolic Processes Important for Alginate Biosynthesis in Azotobacter vinelandii by Screening of a Transposon Insertion Mutant Library

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
Azotobacter vinelandii produces the biopolymer alginate, which has a wide range of industrial and pharmaceutical applications. A random transposon insertion mutant library was constructed from A.

Structural and Phylogenetic Analysis of Rhodobacter capsulatus NifF: Uncovering General Features of Nitrogen-fixation (nif)-Flavodoxins [PDF]

open access: yes, 2013
Analysis of the crystal structure of NifF from Rhodobacter capsulatus and its homologues reported so far reflects the existence of unique structural features in nif flavodoxins: a leucine at the re face of the isoalloxazine, an eight-residue insertion at

Gene dosage analysis in Azotobacter vinelandii. [PDF]

open access: yesGenetics, 1992
Abstract For more than a decade, Azotobacter vinelandii has been considered a polyploid bacterium on the basis of physical studies of chromosome size and DNA content per cell. However, as described in the present work, many genetic operations can be performed in A. vinelandii without the constraints expected in a polyploid bacterium: (i)
