NRX1 targets enzymes of the major H2O2-scavenging pathways. Raw peptide abundance from mass spectrometry analysis of interaction between CAT1, CAT2, and CAT3 as well as APX1 with immobilized NRX1, NRX1(C58,378S), or resin-only (control) columns. Error bars represent SEM (n = 3). Asterisks indicate statistically significant differences compared with the NRX1 control column (*P < 0.05).
