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

Protein and small-molecule microarrays are useful tools for high-throughput analysis of DNA-protein, protein-protein, and protein-small molecule interactions. Here we report on novel microarrays for activity screening of lipases and esterases based on phosphonic acid ester inhibitors. These compounds are activity

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

Lipases are responsible for the hydrolysis of acylglycerols and cholesteryl esters in animals, plants, and microorganisms. In this chapter we describe a tool for the concomitant analysis of lipases in complex proteomes. For this purpose, the target enzymes are selectively
