Enzymes involved in organellar DNA replication in photosynthetic eukaryotes

Frontiers in Plant Science, 2014
Plastids and mitochondria possess their own genomes. Although the replication mechanisms of these organellar genomes remain unclear in photosynthetic eukaryotes, several organelle-localized enzymes related to genome replication, including DNA polymerase,

Human PrimPol mutation associated with high myopia has a DNA replication defect [PDF]

, 2014
PrimPol is a primase-polymerase found in humans, and other eukaryotes, involved in bypassing lesions encountered during DNA replication. PrimPol employs both translesion synthesis and repriming mechanisms to facilitate lesion bypass by the replisome ...

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

FEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

The small subunit of DNA polymerase D (DP1) associates with GINS–GAN complex of the thermophilic archaea in Thermococcus sp. 4557

MicrobiologyOpen, 2019
The eukaryotic GINS, Cdc45, and minichromosome maintenance proteins form an essential complex that moves with the DNA replication fork. The GINS protein complex has also been reported to associate with DNA polymerase. In archaea, the third domain of life,

Evaluation of DNA primase DnaG as a potential target for antibiotics [PDF]

, 2014
Mycobacteria contain genes for several DNA-dependent RNA primases, including dnaG, which encodes an essential replication enzyme that has been proposed as a target for antituberculosis compounds.

The effect of salubrinal on the endoplasmic reticulum stress pathway in heat‐stressed spermatogonial cells in vitro

FEBS Open Bio, EarlyView.
This study investigates the protective role of salubrinal against heat‐induced endoplasmic reticulum (ER) stress in mouse spermatogenic cells (GC1 and GC2). By modulating the ER stress pathway, salubrinal alleviates cellular stress and supports spermatogenic cell survival, suggesting its potential as a therapeutic candidate for heat‐related infertility.

A non-transcriptional function of Yap regulates the DNA replication program in Xenopus laevis

eLife, 2022
In multicellular eukaryotic organisms, the initiation of DNA replication occurs asynchronously throughout S-phase according to a regulated replication timing program.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Forks on the Run: Can the Stalling of DNA Replication Promote Epigenetic Changes?

Frontiers in Genetics, 2017
Built of DNA polymerases and multiple associated factors, the replication fork steadily progresses along the DNA template and faithfully replicates DNA. This model can be found in practically every textbook of genetics, with the more complex situation of

DNA unwinding mechanism of a eukaryotic replicative CMG helicase

Nature Communications, 2020
The DNA duplex is known to be split apart in a steric exclusion manner during replication, but the specific mechanism has remained unclear. Here the authors present a cryo-EM structure of a eukaryotic replicative CMG helicase on forked DNA, revealing the
