Comments
[?]
| Function | Component of the DNA topoisomerase VI involved in chromatin organization and progression of endoreduplication cycles. Relaxes both positive and negative superturns and exhibits a strong decatenase activity. |
| Catalytic activity | Reaction=ATP-dependent breakage, passage and rejoining of double-stranded DNA.; EC=5.6.2.2; |
| Cofactor | Mg(2+) |
| Subunit | Homodimer. Heterotetramer of two TOP6A and two TOP6B subunits. |
| Subcellular location | Nucleus. |
| Similarity | Belongs to the TOP6A family. |
