Inhibitors

Inhibitors Comment Organism Structure
Cu+ presence of Cu+ inhibits noncompetitively with respect to the substrate GSSG and NADPH and inactivates with the cleavage of a peptide bond of the enzyme. Inactivation/fragmentation is prevented by addition of catalase Saccharomyces cerevisiae
Cu2+ presence of Cu2+ inhibits noncompetitively with respect to the substrate GSSG and NADPH and inactivates with the cleavage of a peptide bond of the enzyme. Inactivation/fragmentation is prevented by addition of catalase. Copper binds to sites apart from the substrate sites, causing the peptide cleavage by hydroxyl radical Saccharomyces cerevisiae
H2O2 inactivates with the cleavage of a peptide bond of the enzyme. Inactivation/fragmentation is prevented by addition of catalase Saccharomyces cerevisiae
