Figure 4. . Genomic representation of severe acute respiratory syndrome coronavirus-2 consisting of open reading frames that encode structural and nonstructural proteins, along with their structurally characterized 3D images.

Mutations found when aligning the proteins against their closest homologs such as human SARS-CoV, bat coronavirus BtCoV and bat betacoronavirus BtRf-BetaCoV coronaviruses are highlighted in green and novel protein inserts found in Spike protein are highlighted in blue.
