背景信息

**Background of Nos3 Recombinant Protein**

Nos3. also known as endothelial nitric oxide synthase (eNOS), is a critical enzyme encoded by the *NOS3* gene in humans. It catalyzes the production of nitric oxide (NO) from L-arginine, a signaling molecule essential for regulating vascular tone, blood flow, and endothelial function. NO derived from eNOS plays a pivotal role in maintaining cardiovascular homeostasis, including inhibition of platelet aggregation, smooth muscle relaxation, and modulation of inflammatory responses. Dysregulation of eNOS activity or expression is linked to cardiovascular pathologies such as hypertension, atherosclerosis, and endothelial dysfunction.

Recombinant Nos3 protein is engineered using molecular cloning techniques to enable large-scale production for research and therapeutic applications. The protein is typically expressed in heterologous systems like *E. coli*, yeast, or mammalian cell lines (e.g., HEK293 or CHO cells) to ensure proper folding and post-translational modifications, which are crucial for its enzymatic activity. The recombinant form often includes affinity tags (e.g., His-tag) for simplified purification. Structurally, Nos3 is a homodimer with binding domains for cofactors such as NADPH, flavin mononucleotide (FMN), and calmodulin, which regulate its activity in response to calcium levels.

Studies utilizing recombinant Nos3 focus on elucidating its mechanistic role in vascular biology, drug screening for cardiovascular diseases, and exploring mutations associated with impaired NO signaling. Its application extends to developing therapies targeting endothelial dysfunction or enhancing NO bioavailability. Challenges in production include maintaining stability and activity due to its complex regulation, necessitating optimized expression systems. Overall, recombinant Nos3 serves as a vital tool for advancing cardiovascular research and translational medicine.
