This scenario follows the same methods as scenario A, but it employs the DELTA variant of the SARS-CoV-2 virus. Therefore, the PDB id 7ORB was downloaded. Then the RBD was obtained from the complex and it was prepared following the same procedure as in the control scenario. The RBD of the DELTA variant has two mutations, L452R and T478K, because the RBD isolated from PBD 70RB only has the L452R mutation and lacks the T478K mutation, therefore this mutation was added using the Pymol (R) software. The rest of the protocol is the same as in scenario A.
