    • The HPLC-based BTE equilibrium analyses were conducted as described previously (refs. 3 and 5, each thiol and thioester contained a Tyr residue, and KBTE was measured by determining the relative populations of the four components by using HPLC after equilibration was complete. The 19F NMR-based BTE equilibrium analyses were conducted with fluorine-labeled components; KBTE was measured by determining the relative populations of the four components by using integration of 19F resonances after equilibration was complete. In contrast to this latter approach, Δδ 19F(f2Phe)-based ΔGFold estimates are obtained simply by comparing d 19F(f2Phe) for the full-length thiodepsipeptide and the C-terminal peptide thiol. It is not necessary that equilibrium be attained for this estimation
