Abstract

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 and covalently labelled with fluorescent suicide inhibitors. Stable lipid-protein complexes are formed that are separated by gel electrophoresis and identified by mass spectrometry.
