112 When GSH is oxidized, it forms GSH disulphide, which can be reduced again to GSH with the help of glutathione reductases, another Nrf2 targets, in an NADPH-dependent manner
GTP turnover was then started by adding GTP (5 M) and GDP (10 M), and the amount of remaining GTP was assessed after 10 min incubation at 15 C using the GTPase-Glo assay (Promega)
This reaction is catalyzed by glutathione peroxidase (GPx), producing oxidized GSSG, which is subsequently recycled back to GSH by glutathione reductase
Histamine and tyramine degradation by food fermenting microorganisms
For example, if you have diarrhea or belly pain shortly after eating a food, you might try to eliminate that food, but then find you have similar symptoms with another food and eliminate that one
