背景信息

**Background of SOD2 Recombinant Protein**

Superoxide dismutase 2 (SOD2), also known as manganese-dependent superoxide dismutase (MnSOD), is a mitochondrial enzyme critical for neutralizing reactive oxygen species (ROS). It catalyzes the conversion of superoxide radicals (O₂⁻) into hydrogen peroxide (H₂O₂) and oxygen (O₂), protecting cells from oxidative damage. SOD2 is encoded by the nuclear *SOD2* gene and transported to mitochondria, where its antioxidant activity safeguards mitochondrial DNA, proteins, and membranes. Dysregulation of SOD2 is linked to aging, neurodegenerative diseases (e.g., Alzheimer’s), cancer, and metabolic disorders, highlighting its role in cellular redox balance.

Recombinant SOD2 protein is produced via genetic engineering, often using bacterial (e.g., *E. coli*), yeast, or mammalian expression systems. These systems enable large-scale production of purified, bioactive SOD2 for research and therapeutic applications. Recombinant technology allows modifications, such as tagging for easier purification or stabilization, though challenges remain in preserving its native structure and enzymatic activity post-expression.

Studies leveraging recombinant SOD2 focus on elucidating its mechanisms in oxidative stress-related pathologies and exploring therapeutic potential. For instance, SOD2 supplementation is investigated for mitigating ischemia-reperfusion injury, inflammation, and radiation-induced damage. In biotechnology, recombinant SOD2 is used in cosmetics for anti-aging formulations and in industrial applications to reduce oxidative degradation.

Despite its promise, limitations include short half-life *in vivo* and difficulty crossing cellular membranes. Advances in delivery systems (e.g., nanoparticle encapsulation) and protein engineering aim to enhance its stability and bioavailability. Overall, recombinant SOD2 remains a vital tool for understanding mitochondrial oxidative stress and developing targeted antioxidant therapies.
