Description

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]
• catalyze the hydrolysis of Morita-Baylis-Hillman acetates during enzymatic kinetic resolution of racemic Morita-Baylis-Hillman adducts
• 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.[4]

Biochem/physiol Actions

Lipases catalyze the hydrolysis of carboxylic ester bonds in triacylglycerols to yield glycerol and free fatty acids.[5] 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. Lipolytic products and intermediates formed during lipolysis are involved in various cell-signaling processes.[6] Lipases have broad substrate specificity and high enantioselectivity.[7] This property of lipase makes it a good catalyst in organic synthesis.[1] Lipases play a vital role in fat digestion and metabolism.

Other Notes

1 U corresponds to the amount of enzyme which liberates 1 μmol oleic acid per minute at pH 8.0 and 40 °C (triolein, Cat. No. 62314 as substrate)

Chemoenzymatic synthesis of (-)-carbocyclic 7-deazaoxetanocin G.

Note: When triacetin is used as substrate, the pH is 7.4. Incubation time: 60 minutes.
