英文摘要
The mechanism for initiation of recombination-mediated mitochondrial DNA (mtDNA) replication is still unclear in budding yeast. We revealed that the oxidative DNA damage-excision repair enzyme Ntg1 recognizes the exposed single-strand region at the sites of oxidative modifications and introduces DNA double-stranded breaks at a replication origin. In addition, the 5'-3' exonuclease and DNA helicases play roles in mtDNA replication-mediated by Mhr1, which in vitro prefers relaxed closed circular double-stranded DNA for catalyzing homologous DNA pairing.
