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.

The active form of protein B2, the small subunit of ribonucleotide reductase from E. Coli, contains a binuclear non heme iron center and a tyrosyl radical. MetB2 is an inactive form that lacks the radical but retains the Fe(III) center.
A series of soluble and insoluble polymer supported versions of the versatile oxidizing reagent IBX has been prepared. Each of the reagents were evaluated for their efficiency in the conversion of benzyl alcohol to benzaldehyde. Results from this study were

When the enzymatically active A-fragment of diphtheria toxin is translocated to the cytosol, the B-fragment inserts into the membrane in such a way that a 25-kDa polypeptide becomes shielded from proteases added to the external medium. We have attempted to
Developing potent detoxification strategies for prophylaxis and therapy against organophosphate (OP) intoxication still represents a challenging task. Clinical application of numerous investigated substances including enzymes and low molecular scavengers like metal ions or nucleophiles could not yet be realised due
A previously developed model of exercise-induced muscle contracture using iodoacetate to inhibit glyceraldehyde-3-phosphate dehydrogenase in rat hindlimb muscles produced selective type II myofiber damage. Utilizing a modification of the same model system, rats were given intra-aortic ortho-iodosobenzoic acid (700 nmol/kg
