Thiol peptidase
WebAug 17, 2024 · Introduced in 1994 by Dawson, Muir, Clark-Lewis, and Kent, 37 NCL is a ligation reaction between a C-terminal peptide thioester and an N-terminal cysteinyl peptide. An initial exchange reaction occurs between the thiol and the thioester linking the two peptides via a thioester bond. WebMar 1, 1996 · In all three cell types, extracellular beta-endorphin was metabolized exclusively by a secreted, metal-dependent, thiol peptidase. The enzyme activity is expressed constitutively in EL4 cells and following activation of CD4+ and CD8+ T cells with anti-CD3 antibody. The enzyme is not one of the proteinases associated with cytolytic T cells and ...

The labelled cystine … WebMost of Molecular Probes’ thiol-reactive reagents will react with thiol groups on proteins to give thioether-coupled products. These reagents react rapidly at near-neutral …
WebSulfhydryls, also called thiols, exist in proteins in the side-chain of cysteine (Cys, C) amino acids. Pairs of cysteine sulfhydryl groups are often linked by disulfide bonds (–S–S–) within or between polypeptide chains as the basis of native tertiary or quaternary protein structure. WebMay 11, 2024 · In our model, peptide bonds, in oligomers of thiodepsipeptides and HS-peptides (peptides terminated by thiols instead of amines), are produced by reactions …
