Table 3. Calculated interaction energies (ΔEI-E, in kcal mol-1) for different ionized forms of the inhibitor 17 in a complex with either dGMII or JBMan enzymes at the MP2//BP86 level.
Also overall interaction energies between the enzyme and inhibitor fragment [the pyrrolidine core (ΔEring-E) or the N-2-naphtylmethyl linker (ΔElinker-E)] are also compiled.
