1.11.1.24 additional information Hordeum vulgare the midpoint redox potential of -315 mV places 2-Cys Prx reduction after Calvin cycle activation and before switching the male valve for export of excess reduction equivalents to the cytosol. The activity of the enzyme is also linked to chloroplastic NAD(P)H metabolism. Saline-stress-induced oligomerization of the enzyme triggers membrane attachment and allows for detoxification of peroxides at the site of production in immediate vicinity of the thylakoid membrane ?
