elastin and play an important role as crosslinkers. Structural elucidation of elastin has eluded scientists to date, owing to the highly cross-linked structure and insoluble nature. Therefore, in this study, we aimed to synthesize a desmosine-containing cyclic peptide as a partial elastin mimic, in order to eventually facilitate the elucidation of the crosslinking pattern of elastin by mass spectrometric
弹性蛋白是重要的细胞外基质蛋白,已知在许多组织中具有弹性。它是由弹性蛋白前体原弹性蛋白的自组装和随后的交联形成的。弹力蛋白中仅发现两种基于吡啶鎓的四官能氨基酸的desmosine和isodesmosine,它们在交联剂中起着重要的作用。迄今为止,由于高度交联的结构和不溶性,对弹性蛋白的结构阐明还没有引起科学家的注意。因此,在这项研究中,我们旨在合成一种含去糖素的环肽作为部分弹性蛋白模拟物,以最终通过质谱分析促进阐明弹性蛋白的交联方式。
