Bacterial Cysteine-Inducible Cysteine Resistance Systems [PDF]
Journal of Bacteriology, 2016 ABSTRACT Cysteine donates sulfur to macromolecules and occurs naturally in many proteins. Because low concentrations of cysteine are cytotoxic, its intracellular concentration is stringently controlled. In bacteria, cysteine biosynthesis is regulated by feedback inhibition of the activities of serine acetyltransferase (SAT) and 3-

Possible molecular basis of the biochemical effects of cysteine-derived persulfides
Frontiers in Molecular Biosciences, 2022 Persulfides (RSSH/RSS−) are species closely related to thiols (RSH/RS−) and hydrogen sulfide (H2S/HS−), and can be formed in biological systems in both low and high molecular weight cysteine-containing compounds.

Synthesis, screening, and sequencing of cysteine-rich one-bead one-compound peptide libraries. [PDF]
, 2008 Cysteine-rich peptides are valued as tags for biarsenical fluorophores and as environmentally important reagents for binding toxic heavy metals. Due to the inherent difficulties created by cysteine, the power of one-bead one-compound (OBOC) libraries has

Cysteine metabolic circuitries: druggable targets in cancer
British Journal of Cancer, 2020 To enable survival in adverse conditions, cancer cells undergo global metabolic adaptations. The amino acid cysteine actively contributes to cancer metabolic remodelling on three different levels: first, in its free form, in redox control, as a component
