Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Structural basis for CRISPR RNA-guided DNA recognition by Cascade [PDF]

, 2011
The CRISPR (clustered regularly interspaced short palindromic repeats) immune system in prokaryotes uses small guide RNAs to neutralize invading viruses and plasmids.

The impact of mRNA structure on guide RNA targeting in kinetoplastid RNA editing.

PLoS ONE, 2010
Mitochondrial mRNA editing in Trypanosoma brucei requires the specific interaction of a guide RNA with its cognate mRNA. Hundreds of gRNAs are involved in the editing process, each needing to target their specific editing domain within the target message.

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Protocol: high throughput silica-based purification of RNA from Arabidopsis seedlings in a 96-well format [PDF]

, 2011
The increasing popularity of systems-based approaches to plant research has resulted in a demand for high throughput (HTP) methods to be developed. RNA extraction from multiple samples in an experiment is a significant bottleneck in performing systems ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Structural insights into C-terminus-mediated RNA target cleavage by a mesophilic prokaryotic argonaute

Nature Communications
Prokaryotic Argonaute proteins (pAgos) are programmable nucleases that always utilize DNA guides to cleave DNA targets. Recent studies show that some pAgos preferentially utilize DNA guides to cleave RNA targets rather than DNA targets.

Genome editing in maize directed by CRISPR–Cas9 ribonucleoprotein complexes

Nature Communications, 2016
Genome editing in plants typically requires the expression of Cas9 and guide RNA from stably transformed plasmid DNA. Here, the authors show that successful editing can be achieved after delivery of the Cas9-guide RNA complex as a ribonucleoprotein to ...

Efficient gene editing of pig embryos by combining electroporation and lipofection [PDF]

Veterinary World
Background and Aim: Mosaicism, which is characterized by the presence of wild-type and more than one mutant allele, poses a serious problem in zygotic gene modification through the clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be
