Cutinase is an enzyme that catalyses the degradation of insoluble biopolyester cutin, a structural component of plants. This enzyme has some properties of lipase and esterase. Because of its unique nature, it has potential of being an industrially important enzyme. Some of the useful applications of cutinase include hydrolysis of fats and oils, esterification and transesterification reactions. This enzyme is mainly produced by phytopathogenic fungi, but there are several bacteria which are known to produce cutinase. In this article, the production, purification, characterizations, enhancement of activity and stability, immobilization of the enzyme and its applications in various industries have been discussed.
