WitrynaLMW thiols are synthesized and found in both eukaryotes and prokaryotes. Due to their beneficial role to both eukaryotes and prokaryotes, their specific functions need to be … Witryna10 gru 2012 · In contrast, LMW thiols diminish the nitrosative stress experienced by enzymes, such as glutamine oxoglutarate amidotransferase, that contain redox active cysteines. LMW thiols also preserve the transcription of Salmonella pathogenicity island 2 gene targets from the inhibitory activity of nitrogen oxides. These findings are …

WitrynaHowever, T(SH) 2 levels are usually higher than Gsp and may comprise from 20% to 90% of the total LMW thiol pool [159]. Since trypanosomatids possess functional ISC and CIA machineries and rely on the mitochondrial transporter Atm1 for linking these two pathways [160], a role for LMW thiols in these Fe-S biogenesis pathways would be … WitrynaS-Thiolation of circulating albumin by LMW thiols is the most prevalent Cys 34 oxidative modification. Although the proinflammatory mechanisms mediated by LMW thiols are not yet completely understood, one interesting hypothesis suggests that albumin could be an homocysteine vehicle inside the cells where it could exert its noxious effects.
