The genome of the SARS-CoV-2 virus codes for 28 proteins:
Out of those, 19 have already been characterized structurally. For the rest there are accurate AlphaFold2 predicted structures.
Details of the 3D structure & function of the key proteins & RNA inside the virus can be seen in the NY Times[1].
"The first viral protein created inside the infected cell, ORF1ab, is actually a chain of 16 proteins joined together. Two of these proteins act like scissors, snipping the links between the different proteins and freeing them to do their jobs."[1]
