In the presence of excess amounts of fluorine, a physiological divalent cation, magnesium (Mg(2+)), forms a novel phosphate analogue, magnesium fluoride (MgFn). Park et al. [Biochim. Biophys. Acta 1430, 127-140 (1999)] previously demonstrated that MgADP. MgFn forms a complex with

A homogeneous microplate assay for the serine/threonine protein phosphatases PP1 and PP2A, employing fluorescent-labeled phosphopeptides, has been developed. Phosphopeptides derived from a phosphoacceptor site in myelin basic protein were designed with a cysteine adjacent to the phosphoresidue, allowing site-selective labeling

The fluorogenic reagent 4-(aminosulfonyl)-7-fluoro-2,1,3-benzoxadiazole (ABDF) attenuates the functional activity of the protein tyrosine phosphatase PTP1B by reacting selectively with a single cysteine residue, leaving other cysteines in the protein unmodified. This modification reduces Vmax without substantially affecting substrate binding (Km)

The fluorogenic derivatization reagents with a positive charge, 4-(dimethylaminoethylaminosulfonyl)-7-chloro-2,1,3-benzoxadiazole (DAABD-Cl) and 7-chloro-2,1,3-benzoxadiazole-4-sulfonylaminoethyltrimethylammonium chloride (TAABD-Cl), are proposed for use in proteomics studies. Following derivatization of protein mixtures with these reagents, a series of standard processes of isolation, digestion, and identification of
