Beschreibung

General description

Research area: cell-signaling

Lipase is a hydrolytic enzyme, found ubiquitously in nature. It belongs to the α/β-hydrolases fold family.[1] Lipase structure contains amphipathic helical lid domain in the active site that helps in interfacial activation of protein.[2]

Application

Lipases are used industrially for the resolution of chiral compounds and the transesterification production of biodiesel.

Lipase from Pseudomonas cepacian has been used to:

• catalyze the degradation of polycaprolactone scaffold[3][4]
• catalyze the hydrolysis of Morita-Baylis-Hillman acetates during enzymatic kinetic resolution of racemic Morita-Baylis-Hillman adducts[5]
• as a standard for the generation of a calibration curve to determine the activity of lipase produced by microorganisms isolated from sludge derived from an urban wastewater treatment plant for ethanol production.[6]

Biochem/physiol Actions

Lipases catalyze the hydrolysis of carboxylic ester bonds in triacylglycerols to yield glycerol and free fatty acids.[7][8] Tri-, di-, and monoglycerides are hydrolyzed (in decreasing order of rate). Triacylglycerol lipases specifically hydrolyze the outer links of triacylglycerols and operate exclusively on the water-lipid interface.[9] Lipolytic products and intermediates formed during lipolysis are involved in various cell-signaling processes.[10] Lipases have broad substrate specificity and high enantioselectivity.[11] This property of lipase makes it a good catalyst in organic synthesis.[1] Lipases play a vital role in fat digestion and metabolism.[7]
