Cysteine arylation
… are desired to modify proteins. For decades, cysteine-based reactions with maleimides and alkyl halides are the primary methods for selectively tagging proteins with fluorescent dyes, affinity and radio labels, drug molecules, and polymers and nanocomposites. These traditional reactions …

Long peptides for cysteine arylation
Biological reactivity is typically carried out by large enzymes. There are few examples of reactive, amino-acid-based polymers shorter than 100 residues in length. Of those that do exist, the majority are very short tags (<15 amino acids). Here, we attempted to first discover peptides roughly 30 …

Function and Regulation of Xylem Cysteine Protease 1 and Xylem Cysteine Protease 2 in Arabidopsis
… tracheary element-specific expression of the cysteine protease inhibitor, soyacystatin N in Arabidopsis. Our findings revealed that the absence of XCP2 expression due to T-DNA insertional mutagenesis did not affect plant growth and development in the laboratory. Soyacystatin N was an effective …

Site-selective modification of cysteine residues
… modification methods. The [pi]-clamp-mediated cysteine perfluoroarylation, a novel sequence-selective protein modification strategy, enabled regioselective cysteine modification in the presence of competing cysteines on protein surface. The major goals of this thesis include improving and …

Analysis of a trichomonas vaginalis cysteine protease
… USA. There is increasing focus on the role of cysteine proteases in Trichomonas vaginalis because of their role in virulence of other parasitic protozoa. Determining their location and function will provide insight about their role in the pathogenicity of T. vaginalis and their feasibility as a …

Characterisation of a recombinant human cysteine dioxygenase
Cysteine Dioxygenase is an enzyme that catalyses the reaction of cysteine to cysteinesulfinic acid and is thought to regulate the intracellular concentrations of its substrate. The enzyme may also be involved in the oxidation of exposed sulfidrils of protein and by implication, involved in cell …

Inhibition of Cysteine Protease by Platinum (II) Diamine Complexes
… is found to inhibit several enzymes targeting cysteine, histidine and methionine residues, which are expected to be responsible for its anticancer activity. A better understanding of how the size and shape and leaving ligands of platinum complexes affect cysteine protease, papain enzyme are …

Reactive Peptides for Site-Selective Cysteine and Lysine Bioconjugation
… consists of two peptides: a nucleophilic, cysteine-containing peptide and an electrophilic, perfluoroarylated peptide. The unique sequences of these peptides enhance the reaction rate of a nucleophilic aromatic substitution reaction between these two peptides. Potential favorable …

Investigation of Prestin Membrane Topology by Substituted Cysteine Accessibility Method.
… study prestin’s topological map is substituted cysteine accessibility method. This method requires the introduction of cysteine residues into predicted extracellular or intracellular loops of prestin. Plasmids containing the prestin sequence with the appropriate sitedirected mutations were …

Isolation and characterization of cathepsin Z, a lysosomal cysteine proteinase
Cathepsin Z is a cysteine proteinase found in lysosomes of human cells. It was detected in human cultured cell lines using the peptidyl diazomethane inhibitor Fmoc-Leu-Leu- [¹²⁵]Tyr-CHN₂. The labeling of cathepsin Z by the inhibitor was both time- and concentration-dependent, and the proteinase was …

Complex Formation of Pb(II) with Cysteine, Penicillamine and N-acetylcysteine
… and thiol-containing ligands D-penicillamine, L- cysteine and N-acetyl-L-cysteine were investigated in this study. The complexes formed were studied by 207Pb, 13C, 1H NMR, UV-Vis, ESI-MS, and X-ray absorption spectroscopy. The results of the study provide spectroscopic finger prints for Pb(II) …
