解旋酶是一种特殊的分子马达,可将双链核酸分离成单链。 RecQ 解旋酶家族在细菌和真核细胞的 DNA 复制、重组和修复界面发挥作用。它们是关键的多功能酶,与三种人类疾病有关:布卢姆氏综合症、沃纳氏综合症和罗斯蒙德-汤姆森氏综合症。这篇综述总结了最近将 RecQ 蛋白结构与其生化活性联系起来的研究。
Helicases are specialized molecular motors that separate duplex nucleic acids into single strands. The RecQ family of helicases functions at the interface of DNA replication, recombination and repair in bacterial and eukaryotic cells. They are key, multifunctional enzymes that have been linked to three human diseases: Bloom's, Werner's and Rothmund–Thomson's syndromes. This review summarizes recent studies that relate the structures of RecQ proteins to their biochemical activities.
