For this reason cystine and cysteine were measured together in samples of urine by quantitative sulfhydryl determination after electrolytic reduction. 15 Three control and 2 cystinuric subjects ...

Incubation of cultured rat aortic smooth muscle cells with L-methionine (10 microM or 1 mM) did not result in a significant increase of free intracellular sulfhydryl group content. The L-methionine ...

Iron nitroprusside Fe(II)NP was incorporated into a carbon paste electrode and the electrochemical studies were performed with cyclic voltammetry. The cyclic voltammogram of Fe(II)NP exhibits two ...

The study presents valuable findings on how the hypoxia response pathway senses and responds to changes in the homeostasis of the amino acid cysteine and other sulfur-containing molecules. By ...

It then targets the sulfhydryl of Cys-ketimine via a nucleophilic attack ... Importantly, when the PLP cofactor is occupied by the second L-cysteine, it is anticipated to inhibit persulfide cleavage, ...

For the past few decades, efforts to develop covalent drugs have targeted cysteine. But now another amino acid promises to vastly expand the space of druggable targets: lysine. Cysteine as a ...

These two methods are cysteine-centric and involve non-radioactive labeling, and to some extent, simplify the identification and quantification of palmitoylated proteins. These methods include several ...

Cysteine synthesis was a key step in the origin of life Date: November 12, 2020 Source: University College London Summary: All proteins are built from the same 20 amino acids. One of these ...
