Molybdenum is the only second-row transition metal required by most living organisms, and
is nearly universally distributed in biology. Enzymes containing molybdenum in their active …

Nitrogen is a basic element for life because it is a component of the two preeminent
biological macromolecules: proteins and nucleic acids. Nitrogen exists in the biosphere in …

Nitrogen is present in the environment in a number of oxidation states (Fig. 1).
Interconversion between these oxidation states is predominantly biological (Fig. 1). In this …

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 …

Prokaryotic nitrate reduction can serve a number of physiological roles and can be catalysed
by a number of biochemically distinct nitrate reductases. Three distinct nitrate reductase …

▪ Abstract There was a long-held belief that the gram-positive soil bacterium Bacillus subtilis
is a strict aerobe. But recent studies have shown that B. subtilis will grow anaerobically …

l-Alanosine is a diazeniumdiolate (N-nitrosohydroxylamine) antibiotic that inhibits MTAP-
deficient tumor cells by blocking de novo adenine biosynthesis. Previous work revealed the …

Nitrogen is the mineral nutrient that plants need in the greatest quantities and the one that
most frequently limits plant growth and crop yields. Most plants get their nitrogen (N) from the …

Wastewater with high salinity is one of the major challenges for conventional wastewater
treatment. Although nitrogen management is vital for wastewater treatment, efficient …

There is growing evidence that horizontal gene transfer is a potent evolutionary force in
prokaryotes, although exactly how potent is not known. We have developed a statistical …
