Endoglucanases are a class of enzymes that catalyze the hydrolysis of internal glycosidic linkages in glucan polymers, such as cellulose. These enzymes are produced by various microorganisms, including bacteria, fungi, and some plants. Endoglucanases play a crucial role in the degradation of cellulose, a process known as cellulolysis, which is essential for the breakdown of plant biomass and the release of glucose for energy production.

The structure of endoglucanases typically consists of a catalytic domain that binds to the cellulose substrate and a cellulose-binding domain that enhances the enzyme's affinity for the substrate. The catalytic mechanism involves the cleavage of β-1,4-glycosidic bonds in the cellulose polymer, resulting in the formation of shorter oligosaccharides and glucose units.

Endoglucanases are widely used in industrial applications, such as in the production of biofuels, bioethanol, and bioplastics. They are also employed in the textile industry for the modification of cellulose fibers and in the food industry for the production of enzymes used in baking and brewing. Additionally, endoglucanases have potential applications in medicine, where they can be used to treat diseases caused by bacterial infections that produce cellulose-based biofilms.

The study of endoglucanases continues to be an active area of research, with scientists exploring new ways to enhance their catalytic efficiency, stability, and specificity. Advances in this field have the potential to improve the sustainability of biofuel production, reduce the environmental impact of industrial processes, and develop new therapeutic strategies for human health.
