The search for original protein and biokinetics of antihypertensive peptide derived from Jellyfish Stomolophus nomurai

我发现抗高血压肽YYAPFE来自水母Stomolophus nomurai。该肽不具有源自[Gly-X-Y]n序列的胶原蛋白的特征性三螺旋构象。因此，该肽的原始蛋白质被估计为非胶原蛋白。此外，我还搜索了来自非胶原蛋白的长链肽。一个新的十九肽被鉴定为NKPLAGSPAASELYTEAGG。然而，该肽不具有ACE抑制活性。

I found the antihypertensive peptide YYAPFE derived from Jellyfish Stomolophus nomurai. The peptide has not a characteristic triple-helical conformation of collagen that is derived from the [Gly-X-Y]n sequence. Therefore, the original protein of the peptide was estimated to be non-collagen protein. Furthermore, I searched long chain peptide derived from non-collagen protein. A new nonadecapeptide was identified as NKPLAGSPAASELYTEAGG. However, the peptide has not ACE inhivitory activity.
