The conformational profiles for the endogenous peptide
Opiorphin
and a set of seven analogues exhibiting different inhibitory activities toward human aminopeptidase N (hAPN) and human neprilysin (hNEP) were independently computed to deduce a bioactive conformation that
Opiorphin
may adopt when binding these two enzymes. The conformational space was thoroughly sampled using an iterative simulated annealing protocol, and a library of low-energy conformers was generated for each peptide. Bioactive
Opiorphin
conformations fitting our experimental structure-activity relationship data were identified for hAPN and hNEP using computational pairwise comparisons between each of the unique low-energy conformations of
Opiorphin
and its analogues. The obtained results provide a structural explanation for the dual hAPN and hNEP inhibitory activity of
Opiorphin
and show that the inborn flexibility of
Opiorphin
is essential for its analgesic activity.
