Organocatalytic asymmetric aldol reactions mediated by a cysteine-derived prolinamide
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
In this Letter, a cysteine-derived prolinamide is described to act as a robust and effective organocatalyst for enantioselective aldol reactions. (c) 2008 Elsevier Ltd. All rights reserved.
Modifying glassy carbon (GC) electrodes to confer selectivity for the voltammetric detection of L-cysteine in the presence of DL-homocysteine and glutathione
(Wiley-v C H Verlag Gmbh, 2008-04-01)
In this communication we report a proof of concept study of the use of cyclic voltammetry with a polyeugenol-modified glassy carbon (GC) electrode to selectively detect L-cysteine in the presence of both DL-homocysteine ...
Synthesis and characterization of a platinum(II) complex with N-acetyl-L-cysteine
(Taylor & Francis Ltd, 2009-01-01)
Synthesis and spectroscopic studies in the solid-state of a platinum(II) complex with N-acetyl-L-cysteine are described. Elemental analyses are consistent with composition Pt2(C5H8NO3S)4 center dot 3H2O. Solid-state 13C ...

Protein Topology Determines Cysteine Oxidation Fate: The Case of Sulfenyl Amide Formation among Protein Families
(Public Library of Science, 2015-03)
Cysteine residues have a rich chemistry and play a critical role in the catalytic activity of a plethora of enzymes. However, cysteines are susceptible to oxidation by Reactive Oxygen and Nitrogen Species, leading to a ...
CYANIDE DETERMINATION WITH A MODIFIED NINHYDRIN REAGENT USING N-ACETYL CYSTEINE IN THE PRESENCE OF HEAVY METAL IONS
(Sociedad Chilena de Química, 2010)
In vivo inhibition of cysteine proteases provides evidence for the involvement of ‘senescence-associated vacuoles’ in chloroplast protein degradation during dark-induced senescence of tobacco leaves
(Oxford University Press, 2013-07)
Breakdown of leaf proteins, particularly chloroplast proteins, is a massive process in senescing leaves. In spite of its importance in internal N recycling, the mechanism(s) and the enzymes involved are largely unknown. ...
