The (bis)dansylated sulfonamide 1,2-C6H4(NHSO2C10H6-5-N(CH3)2)2 (1) extracted Pb(II) selectively from water into 1,2-dichloroethane via an ion-exchange mechanism and showed fluorescence quenching upon Pb(II) extraction. The distribution ratios for metal extraction (determined by ICP-MS) for Pb(II) were 133-1410 times higher than those

The structure of human serum albumin (HSA) in the pressure-induced denatured state was investigated by fluorescence spectroscopy. HSA undergoes a conformational change in the pressure range from 0.1 MPa to 400 MPa, at 25 degrees C. Several ligands bind to

The binding interactions of small molecules with carbonic anhydrase II were used as model systems to compare the reaction constants determined from surface- and solution-based biophysical methods. Interaction data were collected for two arylsulfonamide compounds, 4-carboxybenzenesulfonamide (CBS) and 5-dimethyl-amino-1-naphthalene-sulfonamide (DNSA)

Particularly stable elements of noncovalent structure in bovine carbonic anhydrase have been detected and studied. These are present in a highly populated intermediate state formed during denaturation of the enzyme with guanidinium chloride. The intermediate has been detected by analysis
