Theoretical conformational analysis of met‐enkephalin [PDF]

FEBS Letters, 1977
Two pentapeptides, enkephalins (H-Tyr-Gly- Gly-Phe-X-OH, X = Met or Leu), have recently been isolated from mammalian brain [ 11. Subsequent investigations have mainly concentrated on Met- enkephalin which is synonymous with enkephalin in the present paper. It was assumed on the basis of physiological experiments that enkephalin is the endogenous ligand

Exposure to exogenous enkephalins disrupts reproductive development in the Eastern lubber grasshopper, Romalea microptera (Insecta: Orthoptera). [PDF]

PLoS ONE, 2012
Enkephalins play a major role in reproductive physiology in crustaceans; however their role in reproductive development in insects is largely unknown. We investigated the effect of exposure to exogenous leucine-enkephalin (Leu-Enk), methionine-enkephalin

Opioid-like peptides and ghrelin mitigation of bariatric results depends on obesity level

Endokrynologia Polska, 2020
INTRODUCTION: Bariatric surgery, as the only effective treatment of obesity, has strong effects on the metabolism, and nervous and endocrine systems. Thus, based on the different opinions about the efficaciousness of morbid obesity treatments, the aim of

Avian opioid peptides: evolutionary considerations, functional roles and a challenge to address critical questions

Frontiers in Physiology, 2023
The present review considers the putative hormonal opioid peptides in birds. In birds and all other vertebrates, there are four opioid related genes encoding a series of peptides.

Metropolis simulations of Met-Enkephalin with solvent-accessible area parameterizations [PDF]

, 2003
We investigate the solvent-accessible area method by means of Metropolis simulations of the brain peptide Met-Enkephalin at 300$ K$. For the energy function ECEPP/2 nine atomic solvation parameter (ASP) sets are studied. The simulations are compared with

Neuroanatomical distribution of the enkephalinergic and tachykininergic systems in the alpaca brainstem: an immunohistochemical study

Folia Histochemica et Cytobiologica, 2021
INTRODUCTION: A recent study has shown a close neuroanatomical relationship between the enkephalinergic (methionine-enkephalin) and tachykininergic (substance P) systems in the alpaca diencephalon.

Characteristic Temperatures of Folding of a Small Peptide [PDF]

, 1997
We perform a generalized-ensemble simulation of a small peptide taking the interactions among all atoms into account. From this simulation we obtain thermodynamic quantities over a wide range of temperatures.

Endogenous Opioid Levels Do Not Correlate With Itch Intensity and Therapeutic Interventions in Hepatic Pruritus

Frontiers in Medicine, 2021
Background: Chronic pruritus affects up to 70% of patients with immune-mediated hepatobiliary disorders. Antagonists of the μ-opioid receptor (MOR) and agonists of the κ-opioid receptor (KOR) are used to treat hepatic itch, albeit with limited success ...

Comparative Study of Multicanonical and Simulated Annealing Algorithms in the Protein Folding Problem [PDF]

, 1994
We compare a few variants of the recently proposed multicanonical method with the well known simulated annealing for the effectiveness in search of the energy global minimum of a biomolecular system. For this we study in detail Met-enkephalin, one of the
