Atomistic simulations have become one of the main approaches to study the chemistry and dynamics of biomolecular systems in solution. Chemical modelling is a powerful way to understand biochemistry, with a number of different programs available to perform specialized calculations. We present here Q6, a new version of the Q software package, which is a generalized package for empirical valence bond, linear interaction energy, and other free energy calculations. In addition to general technical improvements, Q6 extends the reach of the EVB implementation to fast approximations of quantum effects, extended solvent descriptions and quick estimation of the contributions of individual residues to changes in the activation free energy of reactions.

Isotope effects are subtle but powerful probes of chemical reaction mechanisms and environmental conditions, with applications across chemical, biological and earth sciences. Their meaningful interpretation often relies on calculations based upon fundamental theories for their origin. The SULISO suite consists of four programs for the calculation of vibrational frequencies and isotope effects. CAMVIB is a broad vibrational characterization code developed for analysis of calculated harmonic frequencies and of normal modes in terms of internal coordinates. LIPFR calculates isotopic partition function ratios for pairs of isotopically substituted whole molecules, corresponding to conventional methodology, whereas UJISO is designed to perform similar calculations on subsets of atoms from very large systems. CUTOFF is a utility which truncates a force-constant matrix for a large system to obtain a smaller matrix appropriate for a specified subset of atoms.

DFT calculations for methyl cation complexed within a constrained cage of water molecules permit the controlled manipulation of the “axial” donor/acceptor distance and the “equatorial” distance to hydrogen-bond acceptors. The kinetic isotope effect k(CH3)/k(CT3) for methyl transfer within a cage with a short axial distance becomes less inverse for shorter equatorial C⋅⋅⋅O distances: a decrease of 0.5 Å results in a 3 % increase at 298 K. Kinetic isotope effects in AdoMet-dependent methyltransferases may be m∧odulated by CH⋅⋅⋅O hydrogen bonding, and factors other than axial compression may contribute, at least partially, to recently reported isotope-effect variations for catechol-O-methyltransferase and its mutant structures.

Biomineralisation: avian eggs in focus

Eggs and derived products form an integral part of the food chain. Hence, research into egg structure, function, and production is prevalent. The past decade has seen more than two thousand papers published in relation to avian egg science, these works supplem enting our understanding of the nature of the avian egg, and its biological, chemical, and physical properties. Eggshell colour, strength and chemical composition, poultry nutrition, and genetics and have all been intensively studied recently, with signifi cant progress being made in a number of these areas. Indeed, with the prevalence of robust theoretical techniques, it is now commonplace to combine experimental investigations with theory, providing a balanced and interdisciplinary perspective. There is, h owever, still a gulf of understanding in terms of the structure and formation of the avian egg. In particular, the manner in which the shell itself begins to form on the outer albumin, and the fascinating properties it exhibits.

Early detection through liquid biopsy: breast cancer

Following the successful award of a Cancer Research UK - EPSRC -STFC grant to the ‘Quantum Leapers’ consortium led by Prof Mel Mather (Nottingham) and Dr Philippe Wilson (DMU), the use of novel diamond sensors in early detection is being explored. A strong collaboration between The Universities of Nottingham, De Montfort, Leicester and Queen Mary London is at the heart of this project which seeks to take advantage of nitrogen vacancies within diamond frameworks to understand the early stages of breast cancer development.

Isotope Effect Calculations in the Supramolecular Age

Isotope effects are some of the most subtle yet important probes into reaction mechanism and geometry change, yet some factors that affect their direction and magnitude were still largely unknown. A quick literature search for kinetic isotope effect can produce thousands of results, but how reliable is the data, how reliable are the calculations, and how reliable are the interpretations?In 2014, it was postulated that it was necessary to explore some of the most tenacious questions in the field, by concentrating on a methodological investigation of the nature of isotope effects, and how they are affected by various aspects of the system they represent, such as environment and system size, whilst carrying out method validation on the electronic structure methods employed. After all, understanding interactions on a supramolecular scale begins first by understanding atomic and molecular factors. Therefore, a series of projects designed to explore the basis of the current system and offer robust computational recommendations for the future calculation and interpretation of isotope effects were embarked upon, based on mainly small models as applied to supramolecular systems. Throughout the past few years, the effects of the environment, the vibrational description of the systems, the level of inclusion of molecules within the calculation, and the impact of the original electronic structure methods used to treat these systems have all been considered. Additionally, the SULISO suite of programs has been applied to the calculation of not only organic and enzymic entities, but also organometallic reactions and catalytic cycles, showing the inherent transferability of the SULISO protocols within the chemical field.
