| + | [https://www.uniprot.org/uniprot/PEO1_HUMAN PEO1_HUMAN] Mitochondrial helicase involved in mtDNA replication and repair (PubMed:12975372, PubMed:15167897, PubMed:17324440, PubMed:18039713, PubMed:18971204, PubMed:25824949, PubMed:26887820, PubMed:27226550). Might have a role in mtDNA repair (PubMed:27226550). Has DNA strand separation activity needed to form a processive replication fork for leading strand synthesis which is catalyzed by the formation of a replisome complex with POLG and mtSDB (PubMed:12975372, PubMed:15167897, PubMed:18039713, PubMed:22383523, PubMed:26887820, PubMed:27226550). Preferentially unwinds DNA substrates with pre-existing 5'-and 3'- single-stranded tails but is also active on a 5'- flap substrate (PubMed:12975372, PubMed:15167897, PubMed:18039713, PubMed:22383523, PubMed:26887820, PubMed:27226550). Can dissociate the invading strand of immobile or mobile D-loop DNA structures irrespective of the single strand polarity of the third strand (PubMed:27226550). In addition to its DNA strand separation activity, also has DNA strand annealing, DNA strand-exchange and DNA branch migration activities (PubMed:22383523, PubMed:26887820, PubMed:27226550).<ref>PMID:12975372</ref> <ref>PMID:15167897</ref> <ref>PMID:17324440</ref> <ref>PMID:18039713</ref> <ref>PMID:18971204</ref> <ref>PMID:22383523</ref> <ref>PMID:25824949</ref> <ref>PMID:26887820</ref> <ref>PMID:27226550</ref> Lack DNA unwinding and ATP hydrolysis activities (PubMed:18039713).
