Fidelity of DNA polymerases in the detection of intraindividual variation of mitochondrial DNA
Mitochondrial DNA. Part B. Resources, 2020 Here we investigated the consequences of PCR amplification errors in the identification of intraindividual mtDNA variation. The bumblebee Bombus morio was chosen as model for the COI gene amplification tests with two DNA polymerases (Taq and Q5 ...

Mechanism of Microhomology-Mediated End-Joining Promoted by Human DNA Polymerase Theta
Nature Structural &Molecular Biology, 2014 Microhomology-mediated end-joining (MMEJ) is an error-prone alternative double-strand break–repair pathway that uses sequence microhomology to recombine broken DNA. Although MMEJ has been implicated in cancer development, the mechanism of this pathway is

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

A Well-Conserved Archaeal B-Family Polymerase Functions as an Extender in Translesion Synthesis
mBio, 2022 B-family DNA polymerases (PolBs) of different groups are widespread in Archaea, and different PolBs often coexist in the same organism. Many of these PolB enzymes remain to be investigated.

Mechanism of Suppression of Chromosomal Instability by DNA Polymerase POLQ
PLoS Genetics, 2014 Although a defect in the DNA polymerase POLQ leads to ionizing radiation sensitivity in mammalian cells, the relevant enzymatic pathway has not been identified. Here we define the specific mechanism by which POLQ restricts harmful DNA instability.

FEBS Letters, EarlyView.Knowing how proteases recognise preferred substrates facilitates matching proteases to applications. The S1′ pocket of protease EA1 directs cleavage to the N‐terminal side of hydrophobic residues, particularly leucine. The S1′ pocket of thermolysin differs from EA's at only one position (leucine in place of phenylalanine), which decreases cleavage ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS Letters, EarlyView.Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Fluorescence-Based, High-Throughput DNA Polymerase Assay
BioTechniques, 2002 The commonly used DNA polymerase assay is based on the detection of incorporated radiolabeled nucleotides in a DNA elongation reaction. It is laborious, radioactive, and can be highly variable.

DNA polymerase preference determines PCR priming efficiency
BMC Biotechnology, 2014 BackgroundPolymerase chain reaction (PCR) is one of the most important developments in modern biotechnology. However, PCR is known to introduce biases, especially during multiplex reactions.

FEBS Letters, EarlyView.Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...
