Fig. 4.

Schematic representation of the effect of GSNO on FBPase oxidation based on the in vitro S-nitrosylation assays. The green colour represents reduced subunits and the red colour represents oxidized subunits. The three possible combinations of oxidized and reduced subunits are shown in the 50% oxidized FBPase. The structures were prepared using PyMOL Molecular Graphics software (www.pymol.org). (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
