Living organisms are composed of macromolecules made of hydrogen, carbon, nitrogen,
oxygen, phosphorus and sulfur. Much work has been devoted to the metabolism of the first …

Since their discovery in the 1960s as 'osmotic shock-sensitive'transporters, a plethora of so-
called binding protein-dependent (canonical) ATP-binding cassette (ABC) importers has …

Animals generally require a dietary supply of various nutrients (vitamins, essential amino
acids, etc.) because their biosynthetic capabilities are limited. The capacity of aphids to use …

All flowering plants produce S-methylmethionine (SMM) from Met and have a separate
mechanism to convert SMM back to Met. The functions of SMM and the reasons for its …

Selenium (Se) plays an indispensable role in human nutrition and has been implicated to
have important health benefits, including being a cancer preventative agent. While different …

The ubiquitous cofactor S-adenosyl-L-methionine (SAM) is part of numerous biochemical
reactions in metabolism, epigenetics, and cancer development. As methylation usually …

Angiosperms synthesize S‐methylmethionine (SMM) from methionine (Met) and S‐
adenosylmethionine (AdoMet) in a unique reaction catalyzed by Met S‐methyltransferase …

We determined global transcriptional responses of Escherichia coli K-12 to sulfur (S)-or
nitrogen (N)-limited growth in adapted batch cultures and cultures subjected to nutrient …

Selenium (Se) phytovolatilization, the process by which plants metabolize various inorganic
or organic species of Se (eg selenate, selenite, and Se-methionine [Met]) into gaseous Se …

By providing the bacterial cell with protection against several antibiotics at once,
multiresistance plasmids have an evolutionary advantage in situations where antibiotic …
