Next-generation nutraceuticals: bioactive peptides from plant proteases.

Bioactive peptides are short and specific fragments of proteins with a wide range of biological activities that provide health benefits to the host. These natural peptides are safe and nontoxic and do not show any side effects. Nowadays, the production and characterization of bioactive peptides have been a key area of research as they show great potential as nutraceuticals and functional foods.

Microbial alkaline serine proteases: Production, properties and applications.

Proteolytic enzymes hold a pivotal position in numerous industrial processes where hydrolysis of protein molecules is required under precise conditions. The emerging trend of biotechnological applications in recent years has witnessed a renewed interest in alkaline serine proteases extending their utility in detergent, leather, textile, food and pharmaceutical industries. A variety of microorganisms have been reported to produce alkaline serine proteases on a large scale, however, extensive research to find an alkaline serine protease with desirable characteristics such as significant catalytic efficiency, expanded stability and broad substrate specificity is still ongoing.

A novel thiol-dependent serine protease from sp. N1.

Alkaline proteases have several industrial applications. In the present study, newly isolated sp. N1 was screened as hyper producer of serine protease A multimeric protease of the fungus was purified to homogeneity till 96.
