Linked dimers of the AAA+ ATPase Msp1 reveal energetic demands and mechanistic plasticity for substrate extraction from lipid bilayers

open access: yesFEBS Letters, EarlyView.
Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

Complete genome sequence of Syntrophobacter fumaroxidans strain (MPOB(T)). [PDF]

open access: yes, 2012
Syntrophobacter fumaroxidans strain MPOB(T) is the best-studied species of the genus Syntrophobacter. The species is of interest because of its anaerobic syntrophic lifestyle, its involvement in the conversion of propionate to acetate, H2 and CO2 during ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Genome wide DNA methylation analysis of Haloferax volcanii H26 and identification of DNA methyltransferase related PD-(D/E)XK nuclease family protein HVO_A0006

open access: yesFrontiers in Microbiology, 2015
Restriction-modification (RM) systems have evolved to protect the cell from invading DNAs and are composed of two enzymes: a DNA methyltransferase and a restriction endonuclease. Although RM systems are present in both archaeal and bacterial genomes, DNA

Possible existence of a system similar to bacterial restriction–modification in plants

open access: yesAIMS Molecular Science, 2020
The bacterial restriction–modification (R-M) system has evolved as a defense mechanism against infectious phages and other types of integration of foreign DNA fragments into the host chromosome through recombination.

Fidelity index determination of DNA methyltransferases. [PDF]

open access: yesPLoS ONE, 2013
DNA methylation is the most frequent form of epigenetic modification in the cell, which involves gene regulation in eukaryotes and protection against restriction enzymes in prokaryotes. Even though many methyltransferases exclusively modify their cognate

Nuclear CaMKII enhances histone H3 phosphorylation and remodels chromatin during cardiac hypertrophy. [PDF]

open access: yes, 2013
Calcium/calmodulin-dependent protein kinase II (CaMKII) plays a central role in pathological cardiac hypertrophy, but the mechanisms by which it modulates gene activity in the nucleus to mediate hypertrophic signaling remain unclear. Here, we report that

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins

open access: yesFEBS Letters, EarlyView.
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

Chemical display of pyrimidine bases flipped out by modification-dependent restriction endonucleases of MspJI and PvuRts1I families. [PDF]

open access: yesPLoS ONE, 2014
The epigenetic DNA modifications 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) in eukaryotes are recognized either in the context of double-stranded DNA (e.g., by the methyl-CpG binding domain of MeCP2), or in the flipped-out state (e.g., by ...

Characterization of the Staphylococcus xylosus methylome reveals a new variant of type I restriction modification system in staphylococci

open access: yesFrontiers in Microbiology, 2023
Restriction modification (RM) systems are known to provide a strong barrier to the exchange of DNA between and within bacterial species. Likewise, DNA methylation is known to have an important function in bacterial epigenetics regulating essential ...
