Substitutions in the redox-sensing PAS domain of the NifL regulatory protein define an inter-subunit pathway for redox signal transmission [PDF]
The Per-ARNT-Sim (PAS) domain is a conserved a/ß fold present within a plethora of signalling proteins from all kingdoms of life. PAS domains are often dimeric and act as versatile sensory and interaction modules to propagate environmental signals to ...

Phosphate-limited culture of Azotobacter vinelandii [PDF]
Batch cultures of Azotobacter vinelandii grown in phosphate-deficient media were compared with control cultures grown in phosphate-sufficient media. Phosphate limitation was assessed by total cell yield and by growth kinetics. Although cell protein, nucleic acids, and early growth rate were unaffected by phosphate deficiency, cell wall structure ...

Automatic Control for the Production of Alginate by Azotobacter Vinelandii
Alginates are polymers used in the food and pharmaceutical industries as stabilizing, thickening, gel or film-forming agents. Food coatings formed from alginate have shown to have excellent properties such as flexibility and resistance to tearing.

Negative Cooperativity in the Nitrogenase Fe Protein Electron Delivery Cycle [PDF]
Nitrogenase catalyzes the ATP-dependent reduction of dinitrogen (N2) to two ammonia (NH3) molecules through the participation of its two protein components, the MoFe and Fe proteins.

Electron Transfer Precedes ATP Hydrolysis during Nitrogenase Catalysis [PDF]
The biological reduction of N2 to NH3 catalyzed by Mo-dependent nitrogenase requires at least eight rounds of a complex cycle of events associated with ATP-driven electron transfer (ET) from the Fe protein to the catalytic MoFe protein, with each ET ...

Induction and ultrastructure for cysts of Azotobacter
Within 5 days of induction with n-butanol medium, 98%vegetative cells of Azotobacter vinelandii gave rise to cysts. 91% vegetative cells of Azotobacter chroococcus were converted to cysts. The cysts were spheroids or elliptical whose axe is 1.2 pm to 1.5
