Reaction: NOX4, NOX5 reduce O2 to O2.-

- in pathway: Detoxification of Reactive Oxygen Species
NADPH oxidases 4 and 5 (NOX4, 5) are ER membrane-bound proteins that generates superoxide (O2.-) in endothelial cells (BelAiba et al. 2007). NOX4 functions in association with cytochrome b heterodimer (CYBA:CYBB) on the ER (and nuclear) membrane (Martyn et al. 2006).
