Comparative studies of the cross-linked regions of elastin from bovine ligamentum nuchae and bovine, porcine and human aorta

1. The preparative Edman degradation of desmosine-containing peptides permitted the isolation of peptides C-terminal to the desmosine cross-links in bovine, porcine and human aortic elastin as well as bovine ligamentum nuchae elastin. This identifies the lysines in the tropoelastin which give rise to the desmosine cross-links. 2. The sequences from bovine aortic elastin were identical with those obtained from bovine ligamentum nuchae elastin …
