Recombinant human GBE1 (Glycogen Branching Enzyme 1) is a genetically engineered version of the enzyme encoded by the *GBE1* gene in humans. GBE1 plays a critical role in glycogen metabolism by catalyzing the formation of α-1.6-glycosidic branch points in glycogen molecules, enhancing their solubility and accessibility for energy release. Defects in GBE1 are associated with glycogen storage disease type IV (GSD IV, Andersen disease), a rare autosomal recessive disorder characterized by abnormal glycogen accumulation in tissues, leading to liver cirrhosis, neuromuscular dysfunction, and often early mortality.
The recombinant GBE1 protein is produced using expression systems such as *E. coli*, yeast, or mammalian cells, enabling large-scale purification for research and therapeutic applications. Its production facilitates studies on enzyme kinetics, structural biology, and molecular mechanisms underlying GSD IV. Additionally, recombinant GBE1 holds potential for enzyme replacement therapy (ERT) to address the enzymatic deficiency in affected individuals. Recent advances in protein engineering and gene therapy have further highlighted its utility in developing targeted treatments. Research also explores its role in broader contexts, including metabolic regulation and cellular stress responses. By providing a controlled and consistent enzyme source, recombinant GBE1 supports both diagnostic tool development and innovative therapeutic strategies for glycogen-related disorders.
