Introduction

Glucose oxidase is an oxidoreductase enzyme that catalyses electron transfer from an oxidant to a reluctant. Glucose oxidases use oxygen as an external electron acceptor, resulting in the production of hydrogen peroxide. Glucose oxidase has numerous commercial applications, including improving the colour and taste of food, increasing the persistence of food materials, removing glucose from dried eggs, and removing oxygen from various juices and beverages. Furthermore, glucose oxidase and catalase are used in glucose testing kits (particularly in biosensors) to detect and measure the presence of glucose in industrial and biological solutions. As a result, glucose oxidase is a useful enzyme in industry and medical diagnostics. As a result, determining the structure and function of glucose oxidase is critical for modifying it [1].

The oxidoreductase family, which includes oxidases, oxygenases, peroxidases, dehydrogenases, and other enzymes, catalyses electron transfer from oxidising to reducing agents in living organisms. These enzymes catalyse reactions that include oxygen insertion, hydride transfer, proton extraction, and other critical steps. The oxidised substrate acts as a hydrogen/electron donor in the reaction, while the reduced substrate acts as a hydrogen/electron acceptor. The major cofactors required for oxidoreductase activity are nicotine amide adenine dinucleotide, flavin adenine dinucleotide (FAD), and/or nicotine amide adenine dinucleotide phosphate (NADP).

Glucose oxidase is a holoenzyme composed of two identical 80 kDa subunits that act as redox carriers with the help of various coenzymes. Because of its high specificity, this enzyme is the most advantageous of all similar oxidases. Through catalytic processes, one of these coenzymes, which is an electron carrier, is FAD. The most common type of GOX is A. Niger-derived, with N- or O-glycoside-linked mannose accounting for roughly 80% of their weight. The remaining 20% is due to the amino sugars and other carbohydrates' structural organization. As a result, the molecular weight (MW) of GOX is approximately 130-175 kDa. 13 In contrast to -anomer, d-glucose -anomer is the best substrate for GOX [2].

GOX has a high commercial value; it is widely used and is gaining interest in a variety of industries (including food and beverage processing, pharmaceutical, chemical, medical diagnostics, biotechnology, clinical chemistry, environmental protection, energy, and textile).These composites must meet a general standard. As a result, some of its applications are described briefly below. In the textile industry, there is a lot of interest in replacing chemical bleaching with safer biological bleaching processes. The use of biological bleaching processes in the textile industry is now preferred due to their highly specific, efficient, nontoxic, and ecological characteristics. Chemical bleaching necessitates alkaline pH conditions and temperatures close to boiling. Biological bleaching, on the other hand, can be done at lower temperatures and pH levels, reducing energy consumption and making the process more cost effective. As previously stated, GOX produces H₂O₂ and -d-glucono-lactone, which is then hydrolyzed to gluconic acid. Because d-gluconic acid can chelate metal ions, it is used in bleaching processes that are less harmful to the environment than H₂O₂ [3].

Description

According to the importance of energy conservation, biofuel cells have gained prominence in recent years due to their potential as alternative energy sources. Enzymatic glucose biofuel cells, which can convert the chemical energy in glucose into electricity, are better options for future implantable instruments. GOXs may be the best enzymatic ingredients for developing biofuel cells because they can accelerate the production and transmission of electrons between the substrate of interest and the electrodes. GOXs can act as an anode catalyst, causing electrons to be transferred between the enzyme's active site and the surface of the modified electrode. The main advantages of using GOX are its stability, relatively high biological activity, low cost, and availability of a low-cost substrate [4].

The bacteria that cause dental diseases are well understood. Streptococcus mutans and Streptococcus sobrinus are two microorganisms that can cause dental caries. To date, several strategies have been used to reduce the pathogens' potential. One of them was to improve the peroxidase system, which is part of the innate salivary immunity, by combining GOX, lactoperoxidase, and iodide (or thiocyanate). GOXs are used as antimicrobial agents in oral care products in this regard. The activity of proteolytic enzymes, which are abundant in the oral cavity, can quickly inactivate the oxidase enzyme. This is the H2O2 that acts as a powerful bactericide. Gram-positive bacteria such as S. rattus and S. mutans outnumber Gram-negative bacteria [5].

Conclusion

GOXs can be obtained from a variety of sources. The most common are bacterial, fungal, herbal, and animal sources. Fungi are the most plentiful source and are widely used in industrial applications. Other GOX-rich herbal and fungal sources are thought to be the most common, from which GOXs can be isolated. GOXs derived from A. niger and P. notatum are used in fermentation as an industrial application. Fermentation has been used to produce GOXs for biological processes and clinical trial performance. The GOX was created using the fungi mentioned.

More creativity and significant advances in designing effective biotechnological systems to produce pharmaceutical proteins are required for the discovery of novel vaccines and therapeutic approaches. As a result, selecting an appropriate host and manufacturing conditions play an important role in producing a perfect pharmaceutical product. This product must primarily be thermostable and cost-effective. As a result, fungal GOXs have a wide range of applications and may be suitable products, but their accumulation mechanisms are unknown. Several attempts have been made, however, to optimise these GOXs using genetic modifications.

The study of GOXs is critical due to the numerous industrial, medical, and scientific benefits they provide to humans. Exploring novel types of GOXs using different species may aid in the discovery of better enzyme types with higher activity and stability. The study of enzyme structure can provide us with useful information about its function, which can be used to improve enzyme features. Furthermore, large quantities of the enzyme are required if it is to be used in industry. With some modifications, recombinant GOX production in E. coli, a desirable host, can prepare sufficient amounts of the enzyme of interest. As a result, various aspects of GOX were covered in this review. Because of its higher turnover rate and affinity for the -d-glucose substrate, this fungal GOX was chosen over an A. niger-specific enzyme. The new recombinant proteins are expressed in E. coli's cytoplasm. They can then remain in the cytoplasm or spread to other compartments such as the periplasm. They may be found in either the internal or external membranes. The specific properties of each compartment may provide suitable conditions for recombinant protein expression. Other properties, however, can prevent recombinant production, so various strategies have been developed to overcome these obstacles.
