Term Information

Accession: GO:0003917
Name: DNA topoisomerase type I (single strand cut, ATP-independent) activity
Ontology: molecular_function
Synonyms: type I DNA topoisomerase activity, type I topoisomerase activity, nicking-closing enzyme activity, omega-protein activity, relaxing enzyme activity, swivelase activity, untwisting enzyme activity, DNA topoisomerase I activity, deoxyribonucleate topoisomerase, topoisomerase
Alternate IDs: None
Definition: Catalysis of a DNA topological transformation by transiently cleaving one DNA strand at a time to allow passage of another strand; changes the linking number by +1 per catalytic cycle. Source: PMID:8811192
Comment: Note that a further distinction, between type IA and type IB topoisomerases, is based on sequence or structural similarity between gene products that possess type I catalytic activity.
