Enzyme Information
5.99.1.2 |
DNA topoisomerase.
based on mapping to UniProt P06612
ATP-independent breakage of single-stranded DNA, followed by passage and rejoining.
-!- Brings 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 5.99.1.3).
