Structural insights into human topoisomerase 3β DNA and RNA catalysis and nucleic acid gate dynamics

Abstract Type IA topoisomerases (TopoIAs) are present in all living organisms. They resolve DNA/RNA catenanes, knots and supercoils by breaking and rejoining single-stranded DNA/RNA segments and allowing the passage of another nucleic acid segment through the break. Topoisomerase III-β (TOP3B), the...
