title: Global minimum energy conformations of thyrotropin releasing hormone analogs by simulated annealing. II.
abstract: Lowest conformational energy structures of seventeen thyrotropin releasing hormone analogs have been studied by simulated annealing. A surprising conformational similarity was observed for the peptide backbone. The possible role of each substituent in its biological activity is inferred. A composite hydrogen-bonding environment is proposed for the TRH with respect to receptor binding.
