In line with the Enzyme Commission number (EC number), ‘‘EC1.1.3.4’’ refers to glucose oxidase.
Glucose oxidase, also known as notatin, is a secreted enzyme synthesized predominantly in several species of insects and fungi, such as Aspergillus and Penicillium species which oxidizes glucose into glucolactone, converting oxygen into hydrogen peroxide in the process. Nowadays, glucose oxidase is widely used in diagnostics for measuring the amount of glucose in body fluids, which has made glucose measurement fast, easy, and inexpensive, because of which, it is effective to reduce a variety of complications of diabetes since measures can be taken if the glucose level is tested beyond the standard. Besides, in the last few years, glucose oxidases has become commercially essential in various fields, which can be applied in chemical, pharmaceutical, food, beverage, and other industries.
