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 complete removal of the fluorescent cysteine derivative 4-(aminosulfonyl)-7-fluoro-2,1,3-benzoxadiazole (ABD-F) from an intact protein has not been demonstrated even after extended treatment with a reducing agent. It has been suggested that this may be due to incomplete denaturation under the

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)
