文献和实验毛发、羽毛、角、蹄等的结构(纤维状)蛋白质,有α-角蛋白和β-角蛋白两类。头发和羊毛的基本结构是α-角蛋白,稳定的β-角蛋白有蚕丝和蛛丝的丝心蛋白。α-角蛋白的氨基酸组成和序列均适合构成α-螺旋,它也富含胱氨酸残基,后者提供相邻多肽链间的二硫(—S—S—)桥,这种桥是共价键,因而非常牢固,可使α-螺旋连在一起构成凝聚强度很高的纤维。“硬”角蛋白,如龟壳的α-角蛋白有无数的二硫键。头发的α-角蛋白结构已经电镜和α-射线衍射结构分析,它的3条有α-螺旋结构的多肽链互相缠绕形成类似
DNA Extraction from Keratin and Chitin
DNA extracted from keratinous and chitinous materials can be a useful source of genetic information. To effectively liberate the DNA from these materials, buffers containing relatively high levels of DTT, proteinase K, and detergent
硬蛋白之一。又称角质。是在皮肤细胞最外层形成的毛发、绒毛、羽毛、角、爪、蹄等的主要成分,是动物体具有保护作用的组成蛋白。从氨基酸组成中其显著特点是胱氨酸含量高(绒毛中占11%),角、爪那种愈硬的,含量愈大。肽链是以许多 -S-S-桥连接所形成的网状。极难溶于水中,(仅作某种程度的膨润),不溶于中性溶剂。不易受蛋白酶的作用。像硫化钠(脱毛剂)那样的还原剂,巯基乙酸(水烫发药)、过氧化氢等氧化剂,以及碱等切断 -S-S-键的试剂,作用也都是弱的。将构成毛发和绒毛的角蛋白分子的自然状态称为α
