A-a The trRosetta-generated Receptor-Binding Domain (RBD) structures of all SARS CoV 2 variants were super-imposed on 6M0J. A-b Structural changes between the RBM of 6M0J and the Delta sequence. A-c Structural changes of the RBM between 6M0J and the Omicron sequence. B-a RBM of 6M0J; (1), (2), (3), (4) are the changes observed. B-b Structural changes of the RBM between 6M0J and the Delta sequence. B-c Structural changes of the RBM between 6M0J and the Omicron sequence
