WebSep 6, 2002 · Thiolate anions have been generated in a "demand-based" fashion under virtually neutral conditions for chemoselective deprotection of aryl alkyl ethers. Solvents play the critical role in making the reaction effective and should have high values of epsilon (>30), molecular polarizabilities (>10), and DN (>27) and low values of AN (<14). WebA thiolate anion of cysteine residue within the protein can be oxidized to sulfenic form by H 2 O 2, thus regulating the structure and function of that protein. Autophagy-associated gene 4 (ATG4) is a cysteine protease and participates in the formation of autophagosome [21]. Initially ATG4 cuts the arginine at the C-terminal of LC3 to expose ...
