At low to moderate concentrations, they act as redox signaling mediators important for the normal physiological functioning of cells
Liquid vitamins in your carry-on must not exceed the 3.4 oz volume limit
The histidine imidazole nitrogen, the glycine -amino group, and the glycine carbonyl oxygen coordinate to the Cu ion in a square-planar geometry, creating a stable chelate with a dissociation constant in the femtomolar range
Apart from differential compartmentation, one possibility is that this array of enzymes guarantees robust redox homeostasis, even at the expense of redundancy, consistent with loss-of-function studies for APX and PRX isoforms in the chloroplast (Awad et al
