Five-Substrate Cocktail As A Sensor Array for Measuring Enzyme Activity Fingerprints of Lipases and Esterases

Substrate arrays for measuring enzyme activity fingerprints. can be conveniently formulated as cocktails designed such that the reaction products can be separated and quantified by analytical high-performance liquid chromatography (HPLC). Fingerprinting of lipases and esterases, an important class of microbial enzymes, is reported with a cocktail of only five substrates as a practical fingerprinting reagent. An unusually strong C4-esterase activity was thus revealed in a recently discovered microbial esterase.
