Lmw thiols
Witryna14 lip 2024 · The nucleophilic reaction of LMW thiols with protein Cys residues involved in disulphide bonds produce thiol-disulphide exchange reactions important in the redox buffering and antioxidant protection of cellular proteins. Mixed disulphides (PS-SR) are also produced by the reaction between PSH or PSSG and LMW-SH. Witryna30 paź 2024 · Different organisms utilize different types of LMW thiols. Although cysteine and coenzyme A are present in all organisms, mycothiol and bacillithiol are observed only among Gram-positive bacteria [36,37]. Among eukaryotes, Gram-negative bacteria, and some Gram-positive bacteria, glutathione is the predominant LMW thiol .
