General description

4-(Fluorosulfonyl)benzoic acid is a a xenobiotic substrate analogue which on incubation with 4-4 isozyme of rat liver glutathione S-transferase results in a time-dependent inactivation of the enzyme.

Application

4-(Fluorosulfonyl)benzoic acid was used as an affinity label of dimeric pig lung pi class glutathione S-transferase.

The compound 4-(fluorosulfonyl)benzoic acid (4-FSB) functions as an affinity label of the dimeric pig lung pi class glutathione S-transferase yielding a completely inactive enzyme. Protection against inactivation is provided by glutathione-based ligands, suggesting that the reaction target is near or

Proteins that bind ATP and GTP are important cellular components. We developed an immunological approach to selectively tag nucleotide-binding proteins based on the use of 5'-[4-(fluorosulfonyl)benzoyl]adenosine and 5'-[4-(fluorosulfonyl)benzoyl]guanosine affinity tags and an antibody against 4-(sulfonyl)benzoate. Detection follows affinity labeling, gel
