Discovered in 1975, two forms of enkephalin have been found, one containing leucine, and the other containing methionine. Both are products of the proenkephalin gene. Met-enkephalin is Tyr-Gly-Gly-Phe-Met. Leu-enkephalin has Tyr-Gly-Gly-Phe-Leu. This study aimed at characterizing the neurotransmitter phenotype of enkephalin neurons in the rat amygdaloid complex. We first established the detailed distribution of vesicular glutamate transporters 1 and 2 (VGLUT1 and ‐2) and glutamate decarboxylase 65 (GAD65) in the amygdala by using in situ hybridization.

From Wikipedia, the free encyclopedia Met-enkephalin, also known as metenkefalin (INN), sometimes referred to as opioid growth factor (OGF), is a naturally occurring, endogenous opioid peptide that has opioid effects of a relatively short duration. It is one of the two forms of enkephalin, the other being leu-enkephalin.

Carnosine, the putative excitatory neurotransmitter of olfactory nerves, was found to exert little or no effect in the turtle or the frog olfactory bulb, suggesting that this peptide may have other roles, e.g. neurotropic, in this system. Cathepsin L in secretory vesicles functions as a prohormone-processing enzyme for production of the enkephalin peptide neurotransmitter Sukkid Yasothornsrikul*†, Doron Greenbaum†‡, Katalin F. Medzihradszky‡, Thomas Toneff§, Richard Bundey§, K‐ME production increases during 30 min to 6 h incubation, and ME production increases from 30 min to 18 h incubation. These data demonstrate that cathepsin H possesses aminopeptidase activity to remove NH 2 ‐terminal basic residues for the formation of the (Met)enkephalin peptide neurotransmitter.

Both of these peptides consist of a  Competes with and mimic the effects of opiate drugs. They play a role in a number of physiologic functions, including pain perception and responses to stress. Met Enkephalin is an endogenous opioid peptide neurotransmitter found naturally in the brains of many animals, including humans.

In chicken embryos, enkephalins inhibited substance P release from sensory neurons, which, in turn, reduced pain sensation . Health Benefits of High Enkephalin Levels 1) May Increase Metabolism We show here that secretory vesicle cathepsin L is the responsible cysteine protease of chromaffin granules for converting proenkephalin to the active enkephalin peptide neurotransmitter. The cysteine protease activity was identified as cathepsin L by affinity labeling with an activity-based probe for cysteine proteases followed by mass The neurotransmitters of pain signals in the posterior horn of the spinal cord are glutamate and substance P. Enkephalins decrease the amount of neurotransmitter released and hyperpolarize (make more negative) the postsynaptic membrane, reducing the generation of action potentials and pain perception at the level of the postcentral gyrus. Some drugs primarily affect one neurotransmitter or class of neurotransmitters.
