The N-terminal domain contains 6 conserved cysteines thought to be involved in disulfide bonding and\/or processing. Leu-enkephalins, which is a type of Proenkephalin-B, compete 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. Dynorphin peptides differentially regulate the kappa opioid receptor. Dynorphin A has a typical opiod activity, it is 700 times more potent than Leu-enkephalin.","brand":"ELK Biotechnology","offers":[{"title":"50ug","offer_id":50413951025432,"sku":"EPT300","price":819.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/ELK_4b971878-1d41-4a8c-90eb-e618501e05d2.jpg?v=1751164361","url":"https:\/\/danabiosci.com\/products\/ept300","provider":"Dana Bioscience","version":"1.0","type":"link"}
