3 GO annotations of molecular function

Name Definition
DNA binding Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
DNA topoisomerase type I (single strand cut, ATP-independent) activity 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.
metal ion binding Binding to a metal ion.

1 GO annotations of biological process

Name Definition
DNA topological change The process in which a transformation is induced in the topological structure of a double-stranded DNA helix, resulting in a change in linking number.
