Type 2 DNA topoisomerase 6 subunit B-like (Top6bl)

Component of a topoisomerase 6 complex specifically required for meiotic recombination. Together with SPO11, mediates DNA cleavage that forms the double-strand breaks (DSB) that initiate meiotic recombination.

The complex promotes comfort of positive and negative supercoiled DNA and DNA decatenation via cleavage and ligation cycles. .
