DNA extraction from formalin-fixed tissue: new light from the Deep-Sea [PDF]

, 2010
DNA samples were extracted from ethanol and formalin-fixed decapod crustacean tissue using a new method based on Tetramethylsilane (TMS)-Chelex. It is shown that neither an indigestible matrix of cross-linked protein nor soluble PCR inhibitors impede PCR

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Tyrosines involved in the activity of φ29 single-stranded DNA binding protein.

PLoS ONE, 2019
The genome of Bacillus subtilis phage ϕ29 consists of a linear double-stranded DNA with a terminal protein (TP) covalently linked to each 5' end (TP-DNA).

MND1 and PSMC3IP control PARP inhibitor sensitivity in mitotic cells

Cell Reports, 2023
Summary: The PSMC3IP-MND1 heterodimer promotes meiotic D loop formation before DNA strand exchange. In genome-scale CRISPR-Cas9 mutagenesis and interference screens in mitotic cells, depletion of PSMC3IP or MND1 causes sensitivity to poly (ADP-Ribose ...

Insights into genotoxic effects of electromagnetic fields [PDF]

, 2008
The increasing use of appliances, which generate electromagnetic fields (EMFs), has provoked public concern about their safety. Scientific research into possible health effects however produced conflicting results.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Essential and non-essential DNA replication genes in the model halophilic Archaeon, Halobacterium sp. NRC-1

BMC Genetics, 2007
Background Information transfer systems in Archaea, including many components of the DNA replication machinery, are similar to those found in eukaryotes.

N 6-Methyladenine hinders RNA- and DNA-directed DNA synthesis: application in human rRNA methylation analysis of clinical specimens

Chemical Science, 2015
N 6-Methyladenine (m6A) is the most abundant internal modification on mammalian mRNA. Very recently, m6A has been reported as a potentially important ‘epigenetic’ mark in eukaryotes.

PCNA and XPF cooperate to distort DNA substrates [PDF]

, 2009
XPF is a structure-specific endonuclease that preferentially cleaves 3' DNA flaps during a variety of repair processes. The crystal structure of a crenarchaeal XPF protein bound to a DNA duplex yielded insights into how XPF might recognise branched DNA ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
