补充资料:铰链dna
h-dna又称铰链dna,是三螺旋结构中较为特殊的一种,1987年由mirkin等在一种持粒的酸性溶液中首次发现。h-dna可在任何以镜象重复的寡聚核苷酸中产生(核苷酸序列具有h回文结构)。h-dna的形成始于共聚物内部突环,其中的双链在一边轻微旋转,折叠回去,以生成第一个三股碱基对。这种成核过程建立了一种非平衡的h-dna构型。缠绕与变性导致了其余dna分子负超螺旋松弛。3′和5′一半的多聚嘧啶链都可以作h-dna的给予体链,而形成两种异构体如图3-30所示,它们在构型上是等价的。简言之,h-dna是由部分未缠绕的复合dna中的一个富嘧啶链,经回折同复合体中伸展的富嘌呤链间形成hoogsteen氢键而形成的分子内三螺旋,即dna的双链所形成的三链螺旋。由于形成过程中发生c→c+的转化,故称h-dna。并把这类序列称为h回文序列。
研究还发现在毫摩尔级的mg2+和中性ph下,d(g)30·d(c)30所形成一种由ggc三碱基体组成的嘌呤分子内三螺旋结构(h*-dna),而另外一些研究则发现d(ag)n·d(t)n和d(g)n·d(c)n束道也能形成同时含有h-dna和h*-dna的纽结(nodule)三锭结构。如图3-30,在这个dna结构中,两个三螺旋的顶端含有少数几个未配对的dna碱基,而且由于不同结构间存在大量的链节,因此,纽结dna的形成具有较高的成核能,但延伸能较低(因为单链区较少)。
