Application

HIV Protease Substrate 1 has been used:
  • to study protein structure-function relationships and in the fluorescent assay[1]
  • to evaluate protease inhibitors and for in vitro detection of the HIV-1 protease activity[2]
  • and in protease kinetics to study its enzymatic degradation rates[3]

Biochem/physiol Actions

HIV Protease Substrate 1 is a synthetic peptide sequence that contains the cleavage site (Tyr-Pro) for the human immunodeficiency virus (HIV) Protease. It has two covalently modified amino acids for the detection of cleavage. One modification is the addition of the fluorophore 5-(2-aminoethylamino)-1-naphthalene sulfonate (EDANS) to the glutamic acid residue, while the other one includes the addition of the acceptor chromophore 4c-dimethylaminoazobenzene-4-carboxylate (DABCYL) to the lysine residue. The modified amino acids are on opposite sides of the cleavage site. Spatial orientation and overlap of the DABCYL absorbance with the EDANS emission permit resonance energy transfer between the two moieties. However, when the peptide is cleaved by the HIV protease, the DABCYL group is no longer proximal to the fluorophore.[1]

HIV infection remains incurable to date and there are no compounds targeted at the viral release. We show here HIV viral release is not spontaneous, rather requires caspases activation and shedding of its adhesion receptor, CD62L. Blocking the caspases activation

Current antiretroviral treatments target multiple pathways important for human immunodeficiency virus (HIV) multiplication, including viral entry, synthesis and integration of the DNA provirus, and the processing of viral polyprotein precursors. However, HIV is becoming increasingly resistant to these "combination therapies."

To effectively fight against the human immunodeficiency virus infection/ acquired immunodeficiency syndrome (HIV/AIDS) epidemic, ongoing development of novel HIV protease inhibitors is required. Inexpensive high-throughput screening assays are needed to quickly scan large sets of chemicals for potential inhibitors. We
