Exploiting genetic diversity and gene synthesis to identify superior nitrogenase NifH protein variants to engineer N2-fixation in plants

open access: yesCommunications Biology, 2021
Engineering nitrogen fixation in eukaryotes requires high expression of functional nitrogenase structural proteins, a goal that has not yet been achieved.

Purple sulfur bacteria fix N2 via molybdenum-nitrogenase in a low molybdenum Proterozoic ocean analogue

open access: yesNature Communications, 2021
Biological N2 fixation was key to the expansion of life on early Earth. The N2-fixing microorganisms and the nitrogenase type used in the Proterozoic are unknown, although it has been proposed that the canonical molybdenum-nitrogenase was not used due to

Selenocyanate derived Se-incorporation into the nitrogenase Fe protein cluster

open access: yeseLife, 2022
The nitrogenase Fe protein mediates ATP-dependent electron transfer to the nitrogenase MoFe protein during nitrogen fixation, in addition to catalyzing MoFe protein-independent substrate (CO2) reduction and facilitating MoFe protein metallocluster ...

Functional Nitrogenase Cofactor Maturase NifB in Mitochondria and Chloroplasts of Nicotiana benthamiana

open access: yesmBio, 2022
Engineering plants to synthesize nitrogenase and assimilate atmospheric N2 will reduce crop dependency on industrial N fertilizers. This technology can be achieved by expressing prokaryotic nitrogen fixation gene products for the assembly of a functional

Rhodobacter capsulatus AnfA is essential for production of Fe‐nitrogenase proteins but dispensable for cofactor biosynthesis and electron supply

open access: yesMicrobiologyOpen, 2020
The photosynthetic α‐proteobacterium Rhodobacter capsulatus reduces and thereby fixes atmospheric dinitrogen (N2) by a molybdenum (Mo)‐nitrogenase and an iron‐only (Fe)‐nitrogenase.

Reconstruction of Nitrogenase Predecessors Suggests Origin from Maturase-Like Proteins

open access: yesbioRxiv, 2021
The evolution of biological nitrogen fixation, uniquely catalyzed by nitrogenase enzymes, has been one of the most consequential biogeochemical innovations over life’s history.

Nitrogenase activity associated with codium species from New Zealand marine habitats [PDF]

open access: yes, 1978
Nitrogenase activity, measured as acetylene reduction, was recorded at rates up to 1028 nmol.h \g * dry weight for Codium adhaerens (Cabr.) Ag. var. convolutum Dellow and Codium fragile (Sur.) Hariot subsp.

How many metals does it take to fix N2? A mechanistic overview of biological nitrogen fixation [PDF]

open access: yes, 2006
During the process of biological nitrogen fixation, the enzyme nitrogenase catalyzes the ATP-dependent reduction of dinitrogen to ammonia. Nitrogenase consists of two component metalloproteins, the iron (Fe) protein and the molybdenum-iron (MoFe) protein;

An alternative path for the evolution of biological nitrogen fixation

open access: yesFrontiers in Microbiology, 2011
Nitrogenase catalyzed nitrogen fixation is the process by which life converts dinitrogen gas into fixed nitrogen in the form of bioavailable ammonia. The most common form of nitrogenase today requires a complex metal cluster containing molybdenum (Mo ...

GmTNRP1, associated with rhizobial type‐III effector NopT, regulates nitrogenase activity in the nodules of soybean (Glycine max)

open access: yesFood and Energy Security, 2023
Soybean is a rich source of protein and oil for humans. It forms a symbiotic association with rhizobia to fix atmospheric nitrogen for its growth and development. Rhizobial type‐III effectors act as important signaling molecules in symbiosis.
