Expressibility of comb tensor network states (CTNS) for the P-cluster and the FeMo-cofactor of nitrogenase [PDF]
Electron. Struct. 3, 014001 (2021), 2020 Polynuclear transition metal complexes such as the P-cluster and the FeMo-cofactor of nitrogenase with eight transition metal centers represent a great challenge for current electronic structure methods. In this work, we initiated the use of comb tensor network states (CTNS), whose underlying topology has a one-dimensional backbone and several one ...

Nitrogenase resurrection and the evolution of a singular enzymatic mechanism
eLife, 2023 The planetary biosphere is powered by a suite of key metabolic innovations that emerged early in the history of life. However, it is unknown whether life has always followed the same set of strategies for performing these critical tasks.

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

Efficient sunlight promoted nitrogen fixation from air under room temperature and ambient pressure via Ti/Mo composites [PDF]
Chemical Engineering Journal 451 (2023) 138592, 2022 Photocatalytic nitrogen fixation is an important pathway for carbon neutralization and sustainable development. Inspired by nitrogenase, the participation of molybdenum can effectively activate nitrogen. A novel Ti/Mo composites photocatalyst is designed by sintering the molybdenum acetylacetonate precursor with TiO$_{2}$.

Electron Transfer Precedes ATP Hydrolysis during Nitrogenase Catalysis [PDF]
, 2013 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 ...

An alternative path for the evolution of biological nitrogen fixation
Frontiers 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 ...
