General description
Research area: Cellsignalling. Lipase A Candida Antarctica, CalA is a thermostable, calcium-dependent enzyme with high substrate specificity. CalA comprises of the catalytic triad (Ser184, Asp334, His366) and has an α/β hydrolase structural fold.
Application
Lipases are used industrially for the resolution of chiral compounds and the transesterification production of biodiesel.
Lipase A Candida antarctica immobilized on Immobead 150, recombinant from Aspergillus oryzae has been used in the synthesis of enantiopure (R)-salsolinol and adsorption kinetics studies using Quartz crystal microbalance with dissipation (QCM-D).It has also been used tostudy the esterification of difluorinated alcohols.[1]
Biochem/physiol Actions
Lipase A Candida Antarctica, CalA is highly specific for alcohols and esterifies the trans-isomer of fatty acids. CalA recognizes highly branched acyl groups and is active on alcohols with steric hindrance. CalA catalyzes the production of enantiopure amino acids and aids in the synthesis of chiral cyanohydrins. It may find industrial applications for its thermostable functionality in paper industry.Lipase A Candida antarctica(CAL-A) shows acetyltransferase activity by synthesizing fatty acid esters from certain alcohols and natural oils in an aqueous environment.
Other Notes
1 U corresponds to the amount of enzyme which liberates 1 μmol butyric acid per minute at pH 10.0 and 40°C (tributyrin, Cat. No. 91010, as substrate)
