摘要

DNA拓扑异构酶VI (topo VI)仅存在于古细菌和植物中，在植物中，它是内复制循环进行所必需的。古菌topo VI是一种异源四聚体，含有DNA切割所需的两个a亚基和执行ATP水解的两个B亚基。

MIDGET and the Function of Topoisomerase VI in Arabidopsis

DNA topoisomerase VI (topo VI) is found only in archaeabacteria and plants, and in plants, it is required for the progression of endoreduplication cycles. Archaea topo VI is a heterotetramer containing two A subunits required for DNA cleavage and two B subunits that perform ATP hydrolysis.
