Host proteases
WebTransmembrane serine protease 2 (TMPRSS2) is a host cell-generated protease capable of priming S protein to activate the binding of the SARS-CoV-2 to ACE2 because it consists of the extracellular domain utilized for virus-receptor interaction. 23 In addition to other host cell proteases, TMPRSS2 is a major protease for SARS-CoV-2 infection, and ... WebApr 19, 2024 · Besides host proteases mentioned above, growing evidence suggests that the gut microbiota could potentially contribute to the proteolytic homeostasis within the large intestine. 47 Indeed, the metabolic potential of gut microbes greatly exceeds that of the host since its genetic set is 150 times larger than the human genome. 48 …
