Plants uptake and assimilate nitrogen from the soil in the form of nitrate, ammonium ions,
and available amino acids from organic sources. Plant nitrate and ammonium transporters …

Gases like H2, N2, CO2, and CO are increasingly recognized as critical feedstock in “green”
energy conversion and as sources of nitrogen and carbon for the agricultural and chemical …

Biological nitrogen fixation (BNF) refers to a microbial mediated process based upon an
enzymatic “Nitrogenase” conversion of atmospheric nitrogen (N2) into ammonium readily …

The reduction of dinitrogen to ammonia by nitrogenase reflects a complex choreography
involving two component proteins, MgATP and reductant. At center stage of this process …

Cobalt is a transition metal located in the fourth row of the periodic table and is a neighbor of
iron and nickel. It has been considered an essential element for prokaryotes, human beings …

Abstract Iron-sulfur (Fe/S) proteins are present in virtually all living organisms and are
involved in numerous cellular processes such as respiration, photosynthesis, metabolic …

Nitrogenase harbors three distinct metal prosthetic groups that are required for its activity.
The simplest one is a [4Fe-4S] cluster located at the Fe protein nitrogenase component. The …

Nitrogenases catalyze the reduction of dinitrogen (N 2) gas to ammonium at a complex
heterometallic cofactor. This most commonly occurs at the FeMo cofactor (FeMoco), a [Mo …

Members of the genus Pseudomonas inhabit a wide variety of environments, which is
reflected in their versatile metabolic capacity and broad potential for adaptation to fluctuating …

Lignin represents an untapped resource in lignocellulosic biomass, primarily due to its
recalcitrance to depolymerization and its intrinsic heterogeneity. In Nature, microorganisms …
