Anwendung

Für die Spaltung von Tryptophanyl-Peptid-Bindungen.

Biochem./physiol. Wirkung

2-Iodosobenzoic acid (IBA) may be used to study enzyme structure and activity. IBA is used as an oxidant which oxidizes vicinal sulfhydryls to disulfides (cysteine residues) within enzymes leading to their inactivation or conformational changes. IBA is also used to cleave tryptophanyl peptide bonds.

Rabbit muscle glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was inactivated by peroxynitrite under biologically relevant conditions. The decrease of enzymatic activity followed an exponential function, and the concentration of peroxynitrite needed to inactivate 50% of 7 microM GAPDH (IC50) was 17 microM. Hydroxyl
