They are the spike (S) surface glycoprotein, the envelope (E) protein, the membrane (M) protein, and the nucleocapsid (N) protein.[2, 7, 8] The infection triggers when Spike protein of the SARS‐CoV‐2 (COVID‐19) interacts with the ACE2 (angiotensin‐converting enzyme 2). This evidence concerns the gene ACE2 and COVID-19.
