Inaugural Chemical Science Lectureship announced

We are delighted to announce the winner of the inaugural Chemical Science Lectureship – Professor Kevan Shokat.

The 2013 Chemical Science Lectureship was awarded in the area of chemical biology and the award lecture was given at Challenges in Chemical Biology (ISACS11) in Boston, USA, in July. Professor Shokat was presented with his award by Chemical Science Associate Editor, Professor Tom Muir.

Professor Shokat obtained his Ph.D. at UC Berkeley and following appointments at Stanford University and Princeton University, in 1999 he moved to UC San Francisco to his current appointment as Associate Professor of Cellular and Molecular Pharmacology.

The Shokat Lab’s research is focused on using the tools of synthetic organic chemistry, structural biology, genetics, and mathematical modelling to gain insight into how signalling networks transmit information in normal and disease settings. Their guiding principle is to use chemistry to answer questions that cannot be addressed by the use of biochemistry or genetics— they seek to provide tools, which fill in the gaps left behind by more traditional approaches.

Award Details
The lectureship, which will be awarded annually, will recognize sustained excellence in research by a mid-career scientist within the chemical sciences. The recipient of the Lectureship is selected and endorsed by the Chemical Science Editorial Board.

The recipient will be invited to present a plenary lecture at a relevant International Symposia on Advancing the Chemical Sciences (ISACS); they will also receive a certificate, $2000 and will be invited to contribute to Chemical Science.

The 2014 Chemical Science Lectureship winner will give a plenary lecture at one of the 2014 ISACS meetings:

  • ISACS 13: Challenges in Inorganic Chemistry and Materials Chemistry – July 2014, Dublin, Ireland
  • ISACS 14: Challenges in Organic Chemistry (Synthesis) – August 2014, Shanghai, China
  • ISACS 15: Challenges in Nanoscience – August 2014, San Diego, USA

More information about these conferences will appear on the ISACS website soon.

Two labels, two locations, one protein

Research reported in Chemical Science describes a new method for labelling proteins with two different chemical components at two separate, selected locations on the protein structure.

Scientists in the UK used the local protein microenvironment to control the outcome of reactions between cysteine residues on the surface of a double cysteine mutant of green fluorescent protein (GFP).

They formed sulfonium salts of the two cysteine residues and found that, dependent on the different environments of their α-protons, one underwent an elimination reaction to form a dehydroalanine while the other residue was protected from elimination by another part of the protein. They were able to convert this second sulfonium salt to an azide, presenting two different functional groups on the protein that could react in different ways to label the protein surface.

The team demonstrated that they could successfully label the protein with both an alkyne dye via the azide and a simple thiol via the dehydroalanine, presenting a simple method for site-selective dual labelling of proteins.

Sensing zinc beyond the cell

Research published in Chemical Science describes the design of a new fluorescent probe that can sense ‘mobile’ zinc outside cells by using a targeting peptide that delivers the probe to the extracellular side of the plasma membrane.

Understanding zinc signalling is a significant area of interest in biological studies. Readily-exchangeable or ‘mobile’ zinc is important in human health and has been shown to have a role in the function of the pancreas, prostate and central nervous system. Current fluorescent zinc sensors tend to be based on small molecules that readily diffuse across cell membranes to give information on zinc in the intracellular environment, but it is difficult to predict how these sensors are distributed beyond the cell membrane where it would be useful to monitor zinc ions released by cells.

Scientists in the United States have developed a design for a zinc sensor that is directed the extracellular plasma membrane by attaching the zinc-signalling fluorophore to a membrane-targeting peptide scaffold. The probes can be readily prepared by solid-phase synthesis to insert the targeting peptide between the fluorophore and a fatty acid that anchors the probe to the cell membrane. The scientists conducted live cell imaging experiments that gave a positive signal for zinc in the plasma membranes of the cells.

Dynamic and bio-orthogonal protein assembly along a supramolecular polymer

Scientists from the Netherlands show how supramolecular polymers can be used to steer the assembly of proteins in a reversible, dynamic manner.

Synthetic supramolecular polymers have already shown great potential in the materials field, but their potential to target biological systems has been underexplored until now. This is surprising considering their self-assembling nature, providing access to structures and molecular properties analogous to biological systems.

The synthesis of a mono-functional discotic molecule, forming supramolecular columnar polymers, allows for the site-selective, covalent attachment of proteins. The supramolecular polymer, displaying the proteins along the columns, acts as a dynamic framework; the simultaneous conjugation of two different proteins enables their assembly in close proximity, resulting in efficient energy transfer. The dynamic nature of the protein-conjugated discotic monomers in the supramolecular polymers allows the exchange of supramolecular building blocks between the columns and tuning of protein density.

The concept of supramolecular polymers displaying proteins could bridge the gap between synthetic and biological systems, providing entry to create dynamic multi- and heterovalent protein assemblies with a responsive nature.

Controlling the bonding/debonding of polymer systems

Controlling polymer debonding/rebonding properties using responsive materials is an exciting emerging area of chemistry and it is widely accepted that control of these properties can be achieved by engineering the functional end-groups responsible for monomer dynamic bonding.

Scientists in Germany and Australia report that the control of the bonding/debonding properties in materials obtained by Diels–Alder reactions between difunctional polymeric building blocks can also be governed by entropy considerations such as chain length and branching of the building blocks. They have shown this theoretically and experimentally for two Diels–Alder polymer systems, each based on a different difunctional diene and a common difunctional dienophile.

This interesting finding will help polymer and materials chemists transform the approach they take to designing reversibly/dynamically bonding materials and could aid the development of self-healing materials.

HX-splitting photocatalysis for solar fuels

Photochemical HX splitting reactions (X = halogen) provide a route for solar-to-fuel energy conversion and halogen photoelimination is a critical step in the process.

Scientists in the US have investigated the photoreduction mechanism of a pair of valence-isomeric dirhodium phosphazane complexes and suggest that a common intermediate is accessed in the photochemistry of both mixed-valent and valence-symmetric complexes.

They conclude that halogen photoelimination proceeds by two sequential photochemical reactions: ligand dissociation followed by subsequent halogen elimination, and they hypothesise that complexes that can directly assume a halide-bridged structure will have the highest quantum efficiencies for energy conversion.
