Recombinant Alpha-1 Antitrypsin

OsrAATRecombinant Alpha-1 Antitrypsin 

 

Alphat-1 Antitrypsin (AAT) is a serine protease inhibitor. It protects tissues from enzymes of inflammatory cells, especially neutrophil elastase. If it is deficiency, neutrophil elastase is free to break down elastin, which contributes to the elasticity of the lungs, resulting in respiratory complications such as emphysema, or COPD (chronic obstructive pulmonary disease) in adults and cirrhosis in adults or children. OsrAAT is derived from rice grain, which contains 384 amino acids with a molecular weight of 43.1kD.

3.Secondary structure of OsrATT

 

 4. Biological activity assay of OsrAAT

The secondary structure of OsrAAT was evaluated by comparing the circular dichroism (CD), it shows the secondary structure of OsrAAT is equivalent to pAAT.
