The juggernaut virus, SARS-CoV-2, that has led to the deaths of over 1.7 lakh people across the world uses angiotensin-converting enzyme 2 (ACE2) as its receptor. It enters the human body through interaction between its spike proteins (S1) and the N-terminal region of ACE2 [4], [5]. The receptor binding domain (RBD) of the virus binds with the protease domain (PD) of the ACE2 receptor and forms an RBD-PD complex [4].
