Protein name
RecName: Full=DNA topoisomerase 6 subunit B;
Gene name

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. The B subunit binds ATP.
Catalytic activity Reaction=ATP-dependent breakage, passage and rejoining of double-stranded DNA.; EC=;
Subunit Homodimer. Heterotetramer of two TOP6A and two TOP6B subunits.
Subcellular location Nucleus.
Similarity Belongs to the TOP6B family.
