Methionine-enkephalin, leucine-enkephalin, methionine-enkephalin-Arg6-Phe7 and methionine-enkephalin-Arg6-Gly7-Leu8 in human pheochromocytoma

Life Sciences, 1983
Methionine-enkephalin(met-enkephalin)-, leucine-enkephalin(leu-enkephalin)-, methionine-enkephalin-Arg6-Phe7(met-enkephalin-Arg-Phe)- and methionine-enkephalin-Arg6-Gly7-Leu8(met-enkephalin-Arg-Gly-Leu)-like immunoreactivities(-LI) were studied in 16 pheochromocytomas by radioimmunoassays (RIAs) for these four opioid peptides.

Crystal structure of methionine-enkephalin

Biochemical and Biophysical Research Communications, 1986
The crystal structure of methionine-enkephalin has been determined by X-ray crystallography. There are two independent pentapeptides in the asymmetric unit and both display extended backbone conformations with their side chains arranged alternately below and above the backbone plane.

Demonstration and characterization of immunoreactive methionine-enkephalin, leucine-enkephalin, methionine-enkephalin-Arg6-Gly7-Leu8 and methionine-enkephalin-Arg6-Phe7 in human phaeochromocytoma

Acta Endocrinologica, 1984
Abstract. To elucidate whether or not human phaeochromocytoma contains methionine-enkephalin-Arg6-Gly7-Leu8 (Met-enkephalin-Arg-Gly-Leu) and methionine-enkephalin-Arg6-Phe7 (Met-enkephalin-Arg-Phe) together with methionine-enkephalin (Met-enkephalin) and leucine-enkephalin (Leu-enkephalin), all of which are known to exist in the same precursor molecule

Parallel distribution of methionine-enkephalin-arg6-gly7-leu8 with methionine-enkephalin, leucine-enkephalin and methionine-enkephalin-arg6-phe7 in human and bovine brains

Life Sciences, 1983
Using specific radioimmunoassays(RIAs) for methionine-enkephalin(Met-Enk), leucine-enkephalin(Leu-Enk), methionine-enkephalin-Arg6-Gly7-Leu8 (Met-Enk-Arg-Gly-Leu) and methionine-enkephalin-Arg6-Phe7 (Met-Enk-Arg-Phe), we studied the regional distribution of these opioid peptides in human and bovine brains.

The Journal of Clinical Endocrinology & Metabolism, 1983
Recent studies on the nucleotide sequence of cloned DNA complementary to mRNA for preproenkephalin from bovine adrenal medulla and human pheochromocytoma have revealed that this precursor molecule contains four copies of methionine-enkephalin (Met-Enk) and one copy each of leucine-enkephalin (Leu-Enk), methionine-enkephalin-Arg6-Gly7-Leu8 (Met-Enk-Arg6-

Use of Methionine-Enkephalin Sulfoxide and Leucine-Enkephalin Radio-Immunoassays for the Measurement of Enkephalins in the Rat Brain.

Clinical and Experimental Pharmacology and Physiology, 1989
SUMMARY1. A radio‐immunoassay (RIA) for methionine‐enkephalin sulfoxide was developed and was used to measure methionine‐enkephalin, after oxidation, in the rat brain.2. The RIA was performed together with assays that use commercially available met‐and leu‐enkephalin antisera.3.
