Virus Protease

Virus Protease

The genetic material (DNA or RNA) of viral pathogens contains enzymes called viral proteases. Viral proteases catalyze the cleavage of particular peptide bonds in cellular proteins or viral polyprotein precursors. Viral proteases may attack the scissile peptide bond using various catalytic mechanisms involving either serine, cysteine, or aspartic acid residues. A high degree of specific recognition and cleavage is guaranteed by the enzyme's complementary substrate binding site's selective recognition of these sequence patterns.

The respiratory illness coronavirus disease 2019 (COVID-19) is caused by the SARS-CoV-2 coronavirus (SARS-CoV-2). SARS-CoV-2 entry requires transmembrane protease, serine 2 (TMPRSS2) to prime the initial spike protein. The cell's protease TMPRSS2 breaks open the virus's spike protein after a SARS-CoV-2 virion attaches to a target cell, revealing a fusion peptide.
