核小体分子式:CAS号:性质:是真核生物染色质的基本结构单位。由组蛋白H2A、H2B、H3、H4各两个分子形成扁平圆柱状八聚体,染色质DNA以左手螺旋围绕其上1.75圈约146bp构成。直径11nm,高5.5nm。借组蛋白分子中碱性氨基酸的正电荷和DNA双螺旋中磷酸基负电荷以静电引力维持结构稳定。组蛋白HI在核小体一侧,结合在DNA出入核小体的位点两翼,各覆盖10bp,其功能与染色质进一步集缩有关。有人将包括H1在内的核色质DNA结合长度为166bp的核小体称为染色质体(chromatosome),不包括HI者称核小体的核心颗粒。各染色质体之间为裸露的DNA连接区,其长度因种属而异,一般32~34bp。这种由染色质DNA细丝串联形成的核小体链就是染色体的一级结构,它使染色质DNA在长度上压缩了7~10倍,尚需经多级螺旋化和盘绕折叠,压缩近万倍后才能形成染色体。
