Abstract

A polypeptide was purified from frog brain extracts on the basis of its ability to inhibit alpha-melanotropin release from perifused frog neurointermediate lobes. Based on Edman degradation, amino acid analysis, and peptide mapping, the primary structure of this frog melanotropin-release-inhibiting factor (melanostatin) was determined to be H-Tyr-Pro-Ser-Lys-Pro-Asp-Asn-Pro-Gly-Glu-Asp-Ala-Pro-Ala-Glu-Asp-Met- Ala-Lys-Tyr-Tyr-Ser-Ala-Leu-Arg-His-Tyr-Ile-Asn-Leu-Ile-Thr-Arg-Gln-Arg- Tyr-NH2 . Frog melanostatin belongs to the pancreatic polypeptide/neuropeptide Y/peptide YY family, and the structure of this peptide differs from that of human neuropeptide Y by only one amino acid substitution in position 19. A synthetic replicate of frog melanostatin is coeluted with the native peptide on HPLC and is highly potent in inhibiting alpha-melanotropin secretion in vitro (IC50 = 60 nM).

摘要

一种多肽是从蛙脑提取物中纯化出来的,其依据是它能够抑制从经灌流的蛙神经中间叶释放α-促黑素。基于埃德曼降解法、氨基酸分析和肽图谱分析,确定这种蛙促黑素释放抑制因子(黑素抑制素)的一级结构为H-Tyr-Pro-Ser-Lys-Pro-Asp-Asn-Pro-Gly-Glu-Asp-Ala-Pro-Ala-Glu-Asp-Met-Ala-Lys-Tyr-Tyr-Ser-Ala-Leu-Arg-His-Tyr-Ile-Asn-Leu-Ile-Thr-Arg-Gln-Arg-Tyr-NH2。蛙黑素抑制素属于胰多肽/神经肽Y/肽YY家族,并且该肽的结构与人类神经肽Y的结构仅在第19位有一个氨基酸取代不同。蛙黑素抑制素的合成复制品在高效液相色谱上与天然肽共洗脱,并且在体外抑制α-促黑素分泌方面具有高效力(IC50 = 60 nM)。
