Descripción general
Lipase B or triacylglycerol ester hydrolases belongs to the class of hydrolases.[1] Lipase B from Candida antarctica (CALB) possesses 317 amino acids and a molecular weight of 33 kDa.[2] CALB has a catalytic triad and an open solvent accessible active site.[3] The catalytic triad is usually Ser-His-Asp/Glu which is found in the carboxy terminal of parallel β sheet.[2]
Aplicación
Lipase B Candida antarctica immobilized on Immobead 150, recombinant from yeast has been used:
- in esterification reaction of lauric acid with n-butanol in a biphasic solvent system[1]
- in hydrolysis of fish oil triglycerides[4]
- in screening of enzymes for Morita–Baylis–Hillman (MBH) reaction[5]
Lipases are used industrially for the resolution of chiral compounds and the transesterification production of biodiesel.
Acciones bioquímicas o fisiológicas
Lipase B from Candida antarctica has been shown to be an effective catalyst for the synthesis of esters of ethyl D-glucopyranoside from fatty acids larger than octanoic acid.[6] It has also been found to catalyze a wide variety of organic reactions including many different regio- and enantio-selective syntheses.[7]
Lipases B from Candida antarctica (CALB) is a versatile catalyst for biotransformation reactions.[1] In aqueous media, CALB behaves like an esterase rather than a lipase.[3]
Lipases catalyze the hydrolysis of triacylglycerols into glycerol and free fatty acids.
