FIGURE 2 Ferroptosis Regulation Although the mechanism of ferroptosis is still unclear, some factors that induce or inhibit ferroptosis have recently been found

Modification Yeast imports precusor (3SH) Esterase enzyme forms thiol-acetate ester Export of thiol-acetate (3SHA) Release Yeast imports Glu-thiol precursor -Glutamyl transpeptidase enzyme converts Glu-thiol to Cys-thiol Yeast imports Cys-thiol precursor -Lyase enzyme cleaves cysteine from Cys-thiol precursor Yeast exports free volatile thiol Current research shows that higher IRC7 gene expression, -lyase activity, and thiol release are observed in lower nutrient conditions
