Enzyme Information

5.6.2.2
DNA topoisomerase.
based on mapping to UniProt Q13472
ATP-independent breakage of single-stranded DNA, followed by passage and rejoining.
-!- These enzymes bring about the conversion of one topological isomer of DNA into another, e.g., the relaxation of superhelical turns in DNA, the interconversion of simple and knotted rings of single-stranded DNA, and the intertwisting of single-stranded rings of complementary sequences, cf. EC 5.6.2.3. -!- Formerly EC 5.99.1.2.
