Multiple chromosomes of Azotobacter vinelandii [PDF]

open access: yesJournal of Bacteriology, 1989
The number of copies of the genes leuB, nifH, nifD, and nifK per cell of Azotobacter vinelandii has been determined to be about 80. A beta-lactamase gene was integrated into the A. vinelandii chromosome by single-point crossover. Subsequently, we have been able to detect nearly 80 copies of this beta-lactamase gene per cell of A.

Substitutions in the redox-sensing PAS domain of the NifL regulatory protein define an inter-subunit pathway for redox signal transmission [PDF]

open access: yes, 2011
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 ...

Responses of vertical distribution of microbial communities in rotating and continuous cropping of tobacco soil

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Investigating how soil microorganisms respond to different cropping systems is essential for advancing sustainable agricultural practices. Most prior studies have focused on the surface layers of soil microbiota across various cropping systems, leaving the distribution of these communities at different depths largely unexplored.

Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

open access: yesChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.
