1.11.1.B10 | physiological function |
D-erythroascorbate peroxidase-deficient cells have remarkably increased intracellular reactive oxygen species and methylglyoxal independent of the intracellular D-erythroascorbate content, which leads to activation of catalase-peroxidase and cytochrome c peroxidase, resulting in defects in cell growth, viability, mitochondrial respiration, filamentation and virulence. EAPX1-deficient or EAPX1-overexpressing cells show more sensitivity or resistance against the exogenous H2O2 and menadione, respectively |
