解旋酶是一类解开氢键的酶,而不是一种酶,由水解ATP供给能量来解开DNA的酶。它们常常依赖于单链的存在,并能识别复制叉的单链结构。一般在DNA或RNA复制过程中起到催化双链DNA或RNA解旋的作用。 与解链有关的酶和蛋白质包括:1.单链结合蛋白2.解旋酶 3.拓扑异构酶Ⅰ 4.拓扑异构酶Ⅱ。 在细菌中类似的解旋酶很多,都具有ATP酶的活性,大部分的移动方向是5'→3',但也有3'→5'移到的情况,如n'蛋白在φχ174以正链为模板合成复制形的过程中,就是按3'→5'移动。

The vasa gene encodes an ATP-dependent RNA helicase protein member of the DEAD-box family. The vasa mRNA is initially found as a component of germ plasm in Drosophila and specifically expressed in the germ cell lineage during its germline differentiation.
vasa基因编码DEAD-box家族成员中一种ATP依赖的RNA解旋酶,在生殖系分化过程中发挥着重要的作用。

杆状病毒DNA解旋酶是病毒复制所必需的。
DNA helicases are essential for replication of baculoviruses.
在细胞中,特异性的解旋酶蛋白质复合体决定着该连结体的形成与稳定。
In the cell, this junction is formed and stabilized by specific group helicase proteins.
如果我是酶,我想要做DNA解旋酶,因为这样,我就能了解你的基因。
If I were an enzyme, I would be DNA helicase, so I could unzip your genes.
You then denature again, each one of these strands gets separated, primers bind, turn on the polymerase, a new strand is made.
然后你可以再次使产物链变性,使各链解旋,再结合引物,激活聚合酶,再生成新链
You first separated your DNA, let the primers bind, then turn on the enzyme, and it makes copies of each one of these.
首先解旋DNA双链,使引物结合,接着激活聚合酶,最终得到各链的复制产物
It operates in a similar fashion to DNA polymerase in that it denatures locally or opens up the double stranded DNA, but it's different in that it creates a new polymer from the DNA template in the language of RNA, using RNA nucleotides and not DNA nucleotides.
它的作用机制类似于DNA聚合酶,在局部使DNA双链变性,解旋,但不同的是,它合成了一个基于DNA模板的,使用RNA编码语言的新聚合物,即使用核糖核苷而非脱氧核糖核苷
