Louis B. Hersh abstract: Two aminopeptidases which hydrolyze Met-enkephalin at the Tyr-Gly bond have been solubilized from rat brain membranes and resolved by ion-exchange chromatography. These aminopeptidases are designated MI and Mil based on the order in which they are eluted during ion-ex-change chromatography. The two aminopeptidases can be distinguished kinetically; aminopeptidase MI hydrolyzes L-arginine/3-naphthylamide 17 times faster than L-alanine (3-naphthylamide, while only a 1.7-fold difference is exhibited by aminopeptidase MIL Aminopeptidase Mil exhibits a higher affinity for aminoacid/3-naphthylamides, Met-enkephalin, Leu-enkephalin, and the inhibitor puromycin as com-! R. ecent studies suggest that the opioid peptides Met-enkephalin (Tyr-Gly-Gly-Phe-Met) and Leu-enkephalin (Tyr-Gly-Gly-Phe-Leu) may serve as neurotransmitters (Freder-ickson, 1977; Smith et al., 1976). Since neurotransmitters are generally inactivated shortly after they are released, recent attention has been focused on the mechanism of inactivation of Met-and Leu-enkephalin. Three mechanisms for the in-
