Molecular Docking for the Development of Alternative Therapies against Leishmaniasis

Chemistry Proceedings, 2023
Topoisomerases play a pivotal role in regulating the topological structure of DNA during fundamental processes such as transcription, DNA repair, or DNA replication; because of this, topoisomerases are biological targets in pathogenic microorganisms or ...

DNA replication licensing in somatic and germ cells [PDF]

, 2004
The DNA replication (or origin) licensing system ensures precise duplication of the genome in each cell cycle and is a powerful regulator of cell proliferation in metazoa.

Attenuation of reverse transcriptase facilitates SAMHD1 restriction of HIV-1 in cycling cells

Retrovirology, 2023
Background SAMHD1 is a deoxynucleotide triphosphohydrolase that restricts replication of HIV-1 in differentiated leucocytes. HIV-1 is not restricted in cycling cells and it has been proposed that this is due to phosphorylation of SAMHD1 at T592 in these ...

Adenovirus DNA Replication [PDF]

Cold Spring Harbor Perspectives in Biology, 2013
Adenoviruses have attracted much attention as probes to study biological processes such as DNA replication, transcription, splicing, and cellular transformation. More recently these viruses have been used as gene-transfer vectors and oncolytic agents.

Genome organization of DNA replication timing and its link to chromatin and transcription [PDF]

, 2008
The replication of the genome is a highly organized process. Not every sequence replicates at the same time, instead some genes replicate early, while others replicate later during S phase.

Whole-Exome Sequencing Identifies a Novel POLG Frameshift Variant in an Adult Patient Presenting with Progressive External Ophthalmoplegia and Mitochondrial DNA Depletion

Case Reports in Genetics, 2021
Mitochondrial DNA (mtDNA) depletion syndromes are a group of autosomal recessive disorders associated with a spectrum of clinical diseases, which include progressive external ophthalmoplegia (PEO).

Dynamics of DNA replication loops reveal temporal control of lagging-strand synthesis [PDF]

, 2009
In all organisms, the protein machinery responsible for the replication of DNA, the replisome, is faced with a directionality problem. The antiparallel nature of duplex DNA permits the leading-strand polymerase to advance in a continuous fashion, but ...

An enhancer of DNA replication [PDF]

Journal of Bacteriology, 1988
cmp, a nucleotide sequence element in the plasmid pT181 of Staphylococcus aureus, acts as an enhancer of DNA replication. When cmp is present on an unrelated vector along with the pT181 origin of replication, it increases the ability of the linked pT181 origin to compete with a coresident pT181 plasmid for the initiator protein RepC.

MCM2-7 ring closure involves the Mcm5 C-terminus and triggers Mcm4 ATP hydrolysis

Nature Communications
The eukaryotic helicase MCM2-7, is loaded by ORC, Cdc6 and Cdt1 as a double-hexamer onto replication origins. The insertion of DNA into the helicase leads to partial MCM2-7 ring closure, while ATP hydrolysis is essential for consecutive steps in pre ...
