Lys105 is a GSH and enzyme activator in the GSSCys assay In a first set of experiments, we analysed the effects of the Lys105 replacements on the steady-state kinetics at variable GSSCys and GSH concentrations

Importantly, since both glutamate export and cysteine import via system XcT are tightly linked to ferroptosis regulation, changes in glutamate or cysteine availability resulting from altered 5-OP metabolism could significantly impact cellular susceptibility to oxidative stress (Figure 3E)
