title: Enzymic synthesis of opioid peptides.
abstract: Protected opioid pentapeptides were synthesized by the papain-catalyzed condensation of small synthetic fragments. These peptides, free as well as protected, were identical with those prepared by the dicyclohexylcarbodiimide-1-hydroxybenzotriazole method.
