In the postgenomic era new technologies are emerging for global analysis of protein function. The introduction of active site-directed chemical probes for enzymatic activity profiling in complex mixtures, known as activity-based proteomics has greatly accelerated functional annotation of proteins. Here

We report on a new method for the determination of lipid oxidation in lipoproteins and plasma. The biological lipid system is preloaded with a fluorescent analog of phosphatidylcholine containing diphenylhexatriene (DPH) propionic acid covalently linked to the sn-2 position. When

Lipases and esterases are responsible for carboxylester hydrolysis inside and outside cells and are useful biocatalysts for (stereo)selective modification of synthetic substrates. Here we describe novel fluorescent suicide inhibitors that differ in structure and polarity for screening and discrimination of
H Scholze et al.
Analytical biochemistry, 276(1), 72-80 (1999-12-10)
We report on the determination of active enzyme components in pure and crude lipases, using fluorescent inhibitors for covalent modification and visualization of the enzymatically active proteins. Lipase-specific compounds are triacylglycerol analogs, namely 1,2(2, 3)-di-O-alkylglyceroalkylphosphonic acid-p-nitrophenyl esters, containing a fluorescent
