where Ecomplex is the energy of the non-covalently interacting amino acid and carbohydrate monomer pair, and Ecarbohydrate and EAmino Acid are the energies of each separate component. Energy decomposition analysis was also performed with SAPT0 66,67 using Psi4 v. 1.4 and the aug-cc-pVDZ basis set . Superposition of atomic densities (SAD) guess orbitals and density fitting for the SCF computation with the aug-cc-pVDZ-jkfit auxiliary basis set along with resolution of the identity (i.e., aug-cc-pVDZ-ri) were employed for the SAPT calculations.
