Severe Acute Respiratory Syndrome (SARS), an emerging disease characterized by atypical pneumonia, has recently been attributed to a novel coronavirus (SARS-CoV). The nucleocapsid protein (N) was one of the structural proteins of SARS-CoV (N, S, sE, M). The severe acute respiratory syndrome coronavirus (SARS-CoV) nucleocapsid (N) protein is the most abundant protein in the virus-infected cells. The SARS-CoV-2 S gene has 76% amino acid similarity to the SARS-CoV S gene, and nonsynonymous mutations developed in the S protein as the SARS-CoV epidemic developed, reports have shown that the crystal structure of the SARS-CoV-2 nucleocapsid protein is similar to those of previously described coronavirus N proteins, but their surface electrostatic potential characteristics are distinct.
