Any Cellular Metabolic Process Involving Deoxyribonucleic Acid. This Is One of the Two Main Types of Nucleic Acid Consisting of a Long Unbranched Macromolecule Formed From One or More Commonly Two Strands of Linked Deoxyribonucleotides.
DNA topoisomerase type II (ATP-hydrolyzing) activity
Catalysis of a DNA Topological Transformation by Transiently Cleaving a Pair of Complementary DNA Strands to Form a Gate Through Which a Second Double Stranded DNA Segment Is Passed After Which the Severed Strands in the First DNA Segment Are Rejoined; Product Release Is Coupled to ATP Binding and Hydrolysis; Changes the Linking Number in Multiples of 2.
The Activity of Binding Selectively and Non Covalently to and Distorting the Original Structure of DNA Typically a Straight Helix Into a Bend or Increasing the Bend If the Original Structure Was Intrinsically Bent Due to Its Sequence.
