Protein synthesis by the ribosome is highly dependent on ions. Moreover, the ribosome harbors posttranscriptional and posttranslational modifications, the function of which is poorly understood. Here, we present a high-resolution structure of the E. coli ribosome that suggests how solvation contributes to ribosome integrity and helps to explain the phylogenetic conservation of key elements including post-transcriptional and post-translational modifications.

If advanced biofuels are to replace standard fuels on a gallon-for-gallon basis at competitive pricing, there is a requirement for a new generation of biofuel crops – plants designed specifically to serve as feedstocks for biofuel production. Switchgrass, the US native praire grass, is one of the target crops for biofuel production. In this pilot study we confirmed the capability of proteomics to identify enzymes involved in plant cell wall and sugar biosynthesis using genome resources generated...

Epithelial cells have a natural tendency to close gaps and this feature plays a crucial role in many biological processes such as embryological development and wound healing. Depending on the distribution of extracellular matrix, gap closure occurs through assembly of multicellular actin-based contractile cables and/or cell migration of border cells into the gap. In the absence of cell supporting environment, the closure of non-adhesive gaps is driven exclusively by contraction of multicellular...

How intrinsically disordered proteins can perform a multitude of biological functions without a fixed three-dimensional structure is still a much debated question. Using nuclear magnetic resonance spectroscopy, we have been able to map out the interaction of one such protein with its partner in atomic detail, from its free-state ensemble of conformations via a non-specific encounter complex to the final bound state.

Studies showing that occipital cortex responds to auditory and tactile stimuli after early blindness are often interpreted as demonstrating that early blind subjects ‘see’ auditory and tactile stimuli. One such example is that area hMT+ – a region associated with visual motion processing in sighted – responds to auditory and tactile motion stimuli within early blind individuals. However, to claim that blind subjects ‘see’ using occipital cortex requires that occipital responses directly...

Meiotic recombination is a critical step in gametogenesis for many organisms, enabling the creation of genetically diverse haploid gametes. Regulating the distribution of recombination events so that they are evenly spread across all chromosomes is fundamental for both maintaining genome stability and promoting genetic variation. Here we demonstrate that meiotic DNA breaks (DSBs), the precursors of those recombination events, are not distributed randomly. Moreover, we demonstrate that the evolutionarily...

Transcriptome-wide mapping of the modified base N6-methyladenosine in RNA joins discoveries of methyl-binding proteins and demethylating enzymes to herald the field of ‘epitranscriptomics’ – dynamic post-transcriptional regulation of mRNA analogous to the better known reversible epigenetic modifications of DNA and histone proteins.

Against common intuition, tiny microexons as short as 3 nucleotides can and do exist within our genes. Surprisingly, not only can they be recognized by the cellular machinery and become part of proteins, but they were also often found to be only (or mainly) expressed in neurons. Microexons are switched on during late neuronal differentiation, and impact surfaces of proteins that are crucial for neuronal maturation and synaptic function. Through this protein surface 'microsurgery', microexons...

The epithelial tissues that line our bodies are the frontline protection against the environment and microorganisms. Here, we have discovered how one of these tissues, the cornea, is maintained by a population of specialized progenitor cells located at the edge of the clear tissue.

A better understanding of the mechanisms that regulate ESC identity is needed to fulfill the promise of ESCs in regenerative medicine. Transcription factors and chromatin regulators control the ability of embryonic stem cells (ESCs) to self-renew and remain undifferentiated. An epigenetic reader called BRD4 acts at the boundary between transcription and chromatin remodeling: it binds to acetylated histone tails and recruits RNA Polymerase specifically at key stem cell genes. Genetic and chemical...
