WebMar 29, 2024 · Specifically, the discovery that cysteine residues can be desulfurized to alanine has led to the development of a range of thiol-derived variants of the proteinogenic amino acids that can be...
WebMay 8, 2009 · Thiol oxidoreductases, which are enzymes containing catalytic redox-active Cys residues, have been extensively studied, but even for these proteins there is little understanding of what distinguishes their catalytic redox Cys from other Cys functions. WebNov 17, 2024 · The reactivity of protein Cys thiols is largely dependent on the pK a of their thiol group, as well as the protein microenvironment where the thiol group resides. While many protein Cys thiols retain pK a > 8, and thus, are almost completely protonated (SH) and stable under physiological conditions [10,11], reactive cysteines exhibit relatively ...
WebJan 1, 2024 · An extension of this concept, meant to predict catalytic Cys in thiol oxidoreductases (i.e., enzymes with a catalytic Cys that changes its redox state during catalysis) was based on a special feature of these enzymes: they are the only known enzymes that also use a nonstandard residue, called selenocysteine (Sec) as the … WebThiols are referred to as alkyl mercaptans and named systematically by using the class suffix “thiol” with the appropriate name of the parent hydrocarbon.
