Protein phosphatase 2A (PP2A) is one of the most abundant intracellular serine/threonine (Ser/Thr) phosphatases accounting for 1% of the total cellular protein content. PP2A is comprised of a heterodimeric core enzyme and a substrate-specific regulatory subunit. Potentially, at least seventy

We describe a fluorescence-based assay for the analysis of xylanase activity using a novel fluorogenic substrate, 6,8-difluoro-4-methylumbelliferyl beta-D-xylobioside (DiFMUX(2)). Generation of fluorescent 6,8-difluoro-4-methylumbelliferone (DiFMU) from the substrate corresponded directly to xylanase activity. High-performance liquid chromatography analysis of the digestion products

The fluorogenic substrate 6,8-difluoro-4-methylumbiliferyl phosphate (DIFMUP) has been widely used for the detection of serine and threonine phosphatase activities. Here we describe the use of this substrate for the characterization of protein tyrosine phosphatases (PTPs) and for the screening for
