Kappa-Elastin contains 3.81 lysyl residues per 1000 residues of amino acids. Among these residues, free epsilon-amino groups represent about 16 p. 100, as revealed by guanidination, the buried lysyl residues (buried epsilon-amino groups) represent about 33 p. 100, as revealed by dansylation. After drastic reduction by borohydride, no aldimine bonds were detected and only 6 p. 100 of "deeply buried" amino groups of lysyl residues were detected by a second dansylation. The remaining lysines (about 46 p. 100) are engaged or inaccessible.
κ-弹性蛋白每1000个氨基酸残基中含有3.81个赖氨酰残基。在这些残基中，胍基化显示游离ε-氨基约占100的16%，丹磺酰化显示埋藏的赖氨酰残基（埋藏的ε-氨基）约占100的33%。用硼氢化物剧烈还原后，未检测到醛亚胺键，第二次丹磺酰化仅检测到100中6%的赖氨酰残基“深埋”氨基。其余的赖氨酸（约占100的46%）处于结合状态或无法接近。
