TYROSINASE-CATALYZED OXIDATION OF MET-ENKEPHALINS

Abstract

Kinetic properties of the oxidation of several Met-enkephalins and of kyotorphin by tyrosinase are reported. The opioid peptides tested present an affinity for the enzyme equal or higher than tyrosine itself. Long lasting incubations of these opioid peptides with tyrosinase lead to the formation of DOPA, the presence of ascorbic acid improving the recovery of the aminoacid. Spectrophotometric measurements in the absence of ascorbic acid indicate the formation of dopachrome which reaches the maximum within 15-30 minutes.
