Cys thiol
WebThe recycling of the sulfenic acid back to a thiol is what distinguishes the three enzyme classes. 2-Cys peroxiredoxins are reduced by thiols such as thioredoxins, thioredoxin-like proteins, or possibly glutathione, whereas the 1-Cys enzymes may be reduced by ascorbic acid or glutathione in the presence of GST -π. [7] WebApr 7, 2024 · Forty-two barley malts from 2 to 1500 EBC and five other malted cereals were screened to characterize their thiol precursor profile (G- and Cys- as well as dipeptidic bound CysGly- and γGluCys- forms of 3SHol). First, it was confirmed that G-3SHol was ubiquitous reaching up to 320 µg/kg in some samples, whereas Cys-3SHol remained at …
