Structure of a specific acyl-enzyme complex formed between beta-casomorphin-7 and porcine pancreatic elastase.
Mass spectrometric screening reveals that an unmodified natural heptapeptide--human beta-casomorphin-7, an internal sequence of human beta-casein that possesses opioid-like activity--reacts with porcine pancreatic elastase to form an unusually stable acyl-enzyme complex at low pH. X-ray crystallogra...
