Category:GO:0003917 ! DNA topoisomerase type I (single strand cut, ATP-independent) activity
name: DNA topoisomerase type I (single strand cut, ATP-independent) activity
namespace: molecular_function
def: "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." [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.
