Protein

DNA topoisomerase

Gene

PF3D7_1347100

Organism
Plasmodium falciparum (isolate 3D7)
Status
Unreviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Introduces a single-strand break via transesterification at a target site in duplex DNA. Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand.UniRule annotation

Catalytic activityi

ATP-independent breakage of single-stranded DNA, followed by passage and rejoining.UniRule annotation
