Animal Mitochondrial DNA Replication
(2016-01-01)
Recent advances in the field of mitochondrial DNA (mtDNA) replication highlight the diversity of both the mechanisms utilized and the structural and functional organization of the proteins at mtDNA replication fork, despite ...
Stimulation of Variant Forms of the Mitochondrial DNA Helicase Twinkle by the Mitochondrial Single-Stranded DNA-Binding Protein
(2021-01-01)
Defects in mitochondrial DNA (mtDNA) maintenance may lead to disturbances in mitochondrial homeostasis and energy production in eukaryotic cells, causing diseases. During mtDNA replication, the mitochondrial single-stranded ...
Structure, function and evolution of the animal mitochondrial replicative DNA helicase
(Taylor & Francis Ltd, 2016-01-02)
The mitochondrial replicative DNA helicase is essential for animal mitochondrial DNA (mtDNA) maintenance. Deleterious mutations in the gene that encodes it cause mitochondrial dysfunction manifested in developmental delays, ...
Evolution of the Metazoan Mitochondrial Replicase
(Oxford Univ Press, 2015-04-01)
The large number of complete mitochondrial DNA (mtDNA) sequences available for metazoan species makes it a good system for studying genome diversity, although little is known about the mechanisms that promote and/or are ...
Evolution of the Metazoan Mitochondrial Replicase
(Oxford Univ Press, 2015)
Roles of the mitochondrial replisome in mitochondrial DNA deletion formation
(Soc Brasil Genetica, 2020-01-01)
Mitochondrial DNA (mtDNA) deletions are a common cause of human mitochondrial diseases. Mutations in the genes encoding components of the mitochondrial replisome, such as DNA polymerase gamma (Pol gamma) and the mtDNA ...
Remdesivir triphosphate blocks DNA synthesis and increases exonucleolysis by the replicative mitochondrial DNA polymerase, Pol γ
(2021-11-01)
The COVID-19 pandemic prompted the FDA to authorize a new nucleoside analogue, remdesivir, for emergency use in affected individuals. We examined the effects of its active metabolite, remdesivir triphosphate (RTP), on the ...
Developmental arrest in Drosophila melanogaster caused by mitochondrial DNA replication defects cannot be rescued by the alternative oxidase
(Nature Publishing Group, 2018-07-18)
The xenotopic expression of the alternative oxidase AOX from the tunicate Ciona intestinalis in diverse models of human disease partially alleviates the phenotypic effects of mitochondrial respiratory chain defects. AOX ...
Structural rearrangements in the mitochondrial genome of Drosophila melanogaster induced by elevated levels of the replicative DNA helicase
(Oxford Univ Press, 2018-04-06)
Pathological conditions impairing functions of mitochondria often lead to compensatory upregulation of the mitochondrial DNA (mtDNA) replisome machinery, and the replicative DNA helicase appears to be a key factor in ...
The complete mitochondrial genome sequence of Astyanax paranae (Teleostei: characiformes)
(Taylor & Francis Ltd, 2016-01-01)
Complete mitochondrial genome of the characiform fish Astyanax paranae was characterized in the present study. The whole mitogenome was 16,707 bp long and consisted of 13 protein-coding genes, 22 tRNAs, 2 rRNAs genes, a ...
