WebNov 11, 2024 · Thioether protein crosslinks. Thioether bonds between the sidechains of cysteine and tyrosine have been well studied in cysteine dioxygenases [1], and observed in catalase [2] and galactose oxidase (see examples below). Thioether bonds between cysteine and ligands are common, but are generally not crosslinks between polypeptides. WebMay 14, 2016 · An example, cystathionine (pictured below) is a thioether of cysteine + homoserine or homocysteine + serine (both routes exist) and one enzyme (cystathionine beta-lyase, CβL) can bind the amine on the shorter side, deprotonate the α-carbon and eliminate the thiol (homocysteine) and release the imine (hydrolysed to pyruvate), while a …
