    ABSTRACT: We discuss recent approaches for structure-based protein function annotation. We focus on template-based methods where the function of a query protein is deduced from that of a template for which both the structure and function are known. We describe the different ways of identifying a template. These are typically based on sequence analysis but new methods based on purely structural similarity are also being developed that allow function annotation based on structural relationships that cannot be recognized by sequence. The growing number of available structures of known function, improved homology modeling techniques and new developments in the use of structure allow template-based methods to be applied on a proteome-wide scale and in many different biological contexts. This progress significantly expands the range of applicability of structural information in function annotation to a level that previously was only achievable by sequence comparison.

    ABSTRACT: Force can drive conformational changes in proteins, as well as modulate their stability and the affinity of their complexes, allowing a mechanical input to be converted into a biochemical output. These properties have been utilised by nature and force is now recognised to be widely used at the cellular level. The effects of force on the biophysical properties of biological systems can be large and varied. As these effects are only apparent in the presence of force, studies on the same proteins using traditional ensemble biophysical methods can yield apparently conflicting results. Where appropriate, therefore, force measurements should be integrated with other experimental approaches to understand the physiological context of the system under study.

    ABSTRACT: Many proteins require help from metal cofactors to function properly. Due to the involvement of metal binding, folding of these metalloproteins can be much more complicated. In recent years, several computational methods have been developed to reveal the essential features of metal-coupled protein folding, ranging from quantum mechanics (QM) to atomistic and coarse-grained (CG) simulations. These theoretical tools have achieved great successes in solving the multiscale difficulties arising from metal binding, and provided new insights into the mechanisms of metalloprotein folding. In this review, we first discuss the interaction features of metal-coordination and then introduce several computational models and their applications in metal-coupled folding. Finally we discuss the effects of metal-binding on the protein energy landscape, which is followed by some perspectives. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

    ABSTRACT: Protein folding was the first area of molecular biology for which a systematic statistical-mechanical analysis of dynamics was developed. As a result, folding is described as a process by which a disordered protein chain diffuses across a high-dimensional energy landscape and finally reaches the folded ensemble. Folding studies have produced countless theoretical concepts that are generalizable to other biomolecular processes, such as the functional dynamics of molecular assemblies. Common themes in folding and function include the dominant role of excluded volume, that a balance between energetic roughness and geometrical effects guides dynamics, and that folding/functional landscapes are relatively smooth. Here, we discuss how insights into protein folding have been applied to investigate the functional dynamics of biomolecular assemblies. Copyright © 2014 Elsevier Ltd. All rights reserved.

    ABSTRACT: Biological reactions occur in a highly organized spatiotemporal context and with kinetics that are modulated by multiple environmental factors. To integrate these variables in our experimental investigations of 'native' biological activities, we require quantitative tools for time-resolved in situ analyses in physiologically relevant settings. Here, we outline the use of high-resolution NMR spectroscopy to directly observe biological reactions in complex environments and in real-time. Specifically, we discuss how real-time NMR (RT-NMR) methods have delineated insights into metabolic processes, post-translational protein modifications, activities of cellular GTPases and their regulators, as well as of protein folding events.

    ABSTRACT: Prokaryotic CRISPR-Cas genomic loci encode RNA-mediated adaptive immune systems that bear some functional similarities with eukaryotic RNA interference. Acquired and heritable immunity against bacteriophage and plasmids begins with integration of ∼30 base pair foreign DNA sequences into the host genome. CRISPR-derived transcripts assemble with CRISPR-associated (Cas) proteins to target complementary nucleic acids for degradation. Here we review recent advances in the structural biology of these targeting complexes, with a focus on structural studies of the multisubunit Type I CRISPR RNA-guided surveillance and the Cas9 DNA endonuclease found in Type II CRISPR-Cas systems. These complexes have distinct structures that are each capable of site-specific double-stranded DNA binding and local helix unwinding. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: The increasing appreciation of the central role of non-coding RNAs (miRNAs and long non-coding RNAs) in chronic and degenerative human disease makes them attractive therapeutic targets. This would not be unprecedented: the bacterial ribosomal RNA is a mainstay for antibacterial treatment, while the conservation and functional importance of viral RNA regulatory elements has long suggested they would constitute attractive targets for new antivirals. Oligonucleotide-based chemistry has obvious appeals but also considerable pharmacological limitations that are yet to be addressed satisfactorily. Recent studies identifying small molecules targeting non-coding RNAs may provide an alternative approach to oligonucleotide methods. Here we review recent work investigating new structural and chemical principles for targeting RNA with small molecules.

    ABSTRACT: Bacterial transcription initiation is controlled by sigma factors, the RNA polymerase (RNAP) subunits responsive for promoter specificity. While the primary sigma factor ensures the bulk of transcription during growth, a major strategy used by bacteria to regulate gene expression consists of modifying the RNAP promoter specificity by means of alternative sigma factors. Among these factors, Extra Cytoplasmic Function sigma factors (σ(ECF)) constitute the most abundant group and are generally kept inactive by specific anti-sigma factors that are directly or indirectly sensitive to environmental stimuli. When activated by anti-sigma factor release, σ(ECF) turn on the transcription of dedicated regulons, which trigger adaptive responses for the survival of the cell. Recent structural studies have deciphered the molecular basis for σ(ECF) promoter recognition and original regulatory mechanisms. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: A major challenge facing the community involves identification of mutations that drive cancer. Analyses of cancer genomes to detect, and distinguish, 'driver' from 'passenger' mutations are daunting tasks. Here we suggest that there is a third 'latent driver' category. 'Latent driver' mutations behave as passengers, and do not confer a cancer hallmark. However, coupled with other emerging mutations, they drive cancer development and drug resistance. 'Latent drivers' emerge prior to and during cancer evolution. These allosteric mutations can work through 'AND' all-or-none or incremental 'Graded' logic gate mechanisms. Current diagnostic platforms generally assume that actionable 'driver' mutations are those appearing most frequently in cancer. We propose that 'latent driver' detection may help forecast cancer progression and modify personalized drug regimes. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: The methylotrophic yeast Pichia pastoris is a widely used recombinant expression host. P. pastoris combines the advantages of ease of use, relatively rapid expression times and low cost with eukaryotic co-translational and post-translational processing systems and lipid composition. The suitability of P. pastoris for high density controlled culture in bioreactors means large amounts of protein can be obtained from small culture volumes. This review details the key features of P. pastoris, which have made it a particularly useful system for the production of membrane proteins, including receptors, channels and transporters, for structural studies. In addition, this review provides an overview of all the constructs and cell strains used to produce membrane proteins, which have yielded high resolution structures. Copyright © 2015 The Authors.

    ABSTRACT: The hnRNP K-homology (KH) domain is a single stranded nucleic acid binding domain that mediates RNA target recognition by a large group of gene regulators. The structure of the KH fold is well characterised and some initial rules for KH-RNA recognition have been drafted. However, recent findings have shown that these rules need to be revisited and have now provided a better understanding of how the domain can recognise a sequence landscape larger than previously thought as well as revealing the diversity of structural expansions to the KH domain. Finally, novel structural and functional data show how multiple KH domains act in a combinatorial fashion to both allow recognition of longer RNA motifs and remodelling of the RNA structure. These advances set the scene for a detailed molecular understanding of KH selection of the cellular targets. Copyright © 2015. Published by Elsevier Ltd.

    ABSTRACT: For decades, drug after drug has failed to slow the progression of Alzheimer's disease in human trials. How compounds reducing fibril formation in vitro and toxicity in transgenic mice and flies bind to the Aβ toxic oligomers, is unknown. This account reviews recent drugs mainly targeting Aβ, how they were identified and report their successes from in vitro and in vivo experimental studies and their current status in clinical trials. We then focus on recent in vitro and simulation results on how inhibitors interact with Aβ monomers and oligomers, highly desirable knowledge for predicting new efficient drugs. We conclude with a perspective on the future of the inhibition of amyloid formation by small molecules. Copyright © 2014 Elsevier Ltd. All rights reserved.

    ABSTRACT: The diverse biological functions of intrinsically disordered proteins (IDPs) have markedly raised our appreciation of protein conformational versatility, whereas the existence of energetically favorable yet functional detrimental nonnative interactions underscores the physical limitations of evolutionary optimization. Here we survey recent advances in using biophysical modeling to gain insight into experimentally observed nonnative behaviors and IDP properties. Simulations of IDP interactions to date focus mostly on coupled folding-binding, which follows essentially the same organizing principle as the local-nonlocal coupling mechanism in cooperative folding of monomeric globular proteins. By contrast, more innovative theories of electrostatic and aromatic interactions are needed for the conceptually novel but less-explored 'fuzzy' complexes in which the functionally bound IDPs remain largely disordered.

    ABSTRACT: Recent developments in solid-state NMR have opened the way to the structural analysis of protein fibrils, with the power of studying them at atomic resolution. Solid-state NMR is a relatively new player in the field of structural biology, and reliable approaches to successfully tackle 3D structures have been developed and applied recently. Here we discuss a number of applications to selected fibrils, including prions, α-synuclein and Amyloid-β (Aβ). The latter is, as for its small monomer size, accessible to full 3D structure determination by solid-state NMR. In addition, chemical-shift assignments, from which secondary structure can be directly be determined, is possible for much larger proteins, and has provided important insight in the structural organization of prions and other amyloids playing a central role in disease.

    ABSTRACT: Classically, allostery induces a functional switch through a conformational change. However, lately an increasing number of studies concluded that the allostery they observe takes place through sheer dynamics. Here we explain that even if a structural comparison between the active and inactive states does not detect a conformational change, it does not mean that there is no conformational change. We list likely reasons for this lack of observation, including crystallization conditions and crystal effects; one of the states is disordered; the structural comparisons disregard the quaternary protein structure; overlooking synergy effects among allosteric effectors and graded incremental switches and too short molecular dynamics simulations. Specific functions are performed by distinct conformations; they emerge through specific interactions between conformationally selected states. Copyright © 2014 Elsevier Ltd. All rights reserved.
