BACKGROUND HIV protease (PR) is a virus-encoded aspartic protease that is essential for viral replication and infectivity. The fully active and mature dimeric protease is released from the Gag-Pol polyprotein as a result of precursor autoprocessing. RESULTS We here describe a simple model system to directly examine HIV protease autoprocessing in transfected mammalian cells. A fusion precursor...

Quality feed in aquaculture is very important to increase the growth and health of fish. Low efficiency can be overcome by supplementation using catalytic enzymes. One enzymes that stimulate digestion protease red ginger plants. The enzyme plants plays a role breaking peptide bonds place carboxyl groups so peptides are formed from complex compounds into simpler compounds. This study aims determ...

Proteases are the most important group of the enzymes produced commercially and industrial purpose[1,2]. They have extensive applications in a range of industrial products and processes including detergents, food, pharmaceuticals and leather[3,4]. They are classified into various groups such as alkaline protease, serine protease, cystein protease, aspartic protease and metallo protease[5]. Prot...
