An unknown coronavirus that emerged sometime at the end of 2019 in China, the novel SARS-CoV-2, now called COVID-19, has spread all over the world. Several efforts have been made to prevent or treat this disease, though not with success. The initiation of COVID-19 viral infection involves specific binding of SARS-CoV-2 to the host surface of the receptor, ACE2. The ACE2- SARS-CoV-2 complex then gets transferred into the endosomes where the endosomal acidic proteases cleave the S protein present in SARS-CoV-2, activating its fusion and release of the viral genome. We have carried out detailed and thorough
