Description:
The conformation of [Leu5]enkephalin is produced by a Tyr-Gly-Gly-Phe beta bend stabilized by antiparallel hydrogen bonding between tyrosine and phenylalanine. On the basis of a comparison of the observed structure with the structure of known opiate agonists, three hydrophilic and two hydrophobic regions have been identified as contributing to the recognition of the molecule at the opiate receptor site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, D -- Griffin, J F -- New York, N.Y. -- Science. 1978 Mar 17;199(4334):1214-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/204006" target="_blank"〉PubMed〈/a〉
