    ACE2-like carboxypeptidase B38-CAP protects from SARS-CoV-2-induced lung injury

    Angiotensin-converting enzyme 2 (ACE2) is a receptor for cell entry of SARS-CoV-2, and recombinant soluble ACE2 protein inhibits SARS-CoV-2 infection as a decoy. ACE2 is a carboxypeptidase that degrades angiot...
