Enzymes in Recombinant Proteins

Lipases belong to the family of esterases and naturally act on triglycerides at lipid-water interfaces. Lipases/esterases can be used as versatile tools in hydrolytic reactions, esterifications and transesterification reactions in industrial and food applications. The CalB02 lipase has a temperature optimum in the 40 - 50 °C range and pH optimum between pH 5 and 8.

Alcohol dehydrogenase (EC 1.1.1.1) is the enzyme that catalyzes interconversion between alcohols and aldehydes or ketones, using NAD+/NADH as a cofactor in the following reaction: CH3CH2OH + NAD+ ⇔ CH3CHO + NADH + H+     One unit of alcohol dehydrogenase will convert 1.0 µmol of ethanol to acetaldehyde per minute at pH 8.8 and 25 °C.

Recombinant Isocitrate Dehydrogenase is a bioengineered enzyme, which is derived from microbial or eukaryotic expression systems designed to mirror its naturally occurring form. This enzyme catalyzes the oxidative decarboxylation of isocitrate to alpha-ketoglutarate, utilizing NADP+ as a cofactor in the process. Its mode of action involves the conversion of isocitrate to alpha-ketoglutarate with the concomitant reduction of NADP+ to NADPH.

Glucosidases are enzymes belonging to the family of oxidoreductases. They catalyse the hydrolysis of starches to simple sugars. Glucosidase is widely used in the food, carbohydrate and biofuels industries. In recent years, its applicability has expanded to biotechnology for its potential application in bioenzymatic fuel cells.

Superoxide dismutase is an enzyme that catalyzes the conversion of harmful superoxide into hydrogen peroxide and oxygen.
