| dynorphin | <protein> Opiate peptide derived from the hypothalamic precursor pro dynorphin (that also contains the neoendorphin sequences). Contains the penta peptide leu enkephalin sequence. Its binding affinity is greater for the _ type than for the _ type opioid receptor. (18 Nov 1997) |

| dynorphin-converting endopeptidase | <enzyme> Enzyme from human cerebrospinal fluid; cleaves dynorphin a and b and neoendorphin at the arg(6)-arg(7) or arg(6)-lys(7) bonds Registry number: EC 3.4.21.- Synonym: dynorphin-neo-endorphin endopeptidase, dc-endopeptidase (26 Jun 1999) |
| dynorphins | <chemical> A class of opioid peptides including dynorphin a, dynorphin b, and smaller fragments of these peptides. Dynorphins prefer kappa-opioid receptors (receptors, opioid, kappa) and have been shown to play a role as central nervous system transmitters. Chemical name: Dynorphin (12 Dec 1998) |
