Table 1.

Estimated values of the binding affinity (pKi) and interaction energies for the peptide WG-9-ACE complex.

System pKi (μM) Binding energy (KJ/mol) Intermolecular energy (KJ/mol) Steric and hydrogen-bonding energy (KJ/mol) Electrostatic energy (KJ/mol)
WG-9-N-domain 24.22 −241.0 −13.13 −210.8 −16.0
WG-9-C-domain 25.31 −245.0 −13.13 −214.0 −18.2

ACE = angiotensin-converting enzyme.
