Lipase B from Candida antarctica (CalB), recombinant expressed in Aspergillus oryzae, is a high-quality enzyme preparation supplied as a beige powder with an approximate specific activity of 9 U/mg. This recombinant lipase exhibits excellent catalytic efficiency, broad substrate specificity, and high enantioselectivity, making it a valuable biocatalyst for research, biotechnology, and industrial applications.

CalB belongs to the alpha/beta hydrolase-fold family and consists of 317 amino acids with an approximate molecular weight of 33 kDa. It functions in both aqueous and non-aqueous reaction systems and is widely used for esterification, transesterification, hydrolysis, kinetic resolution, and polymerization reactions.

Researchers utilize this recombinant lipase for enzyme characterization studies, asymmetric synthesis, chiral compound production, biodiesel research, green polymer recycling, and biocatalytic process development.

Overview
