Xylanases have several industrial uses, particularly in baking, modification of animal feed and in pulp bleaching in the paper industry. Process conditions in kraft pulp bleaching generally favour an enzyme that is active at high pH values. The activ

The two established thermal properties of enzymes are their activation energy and their thermal stability, but experimental data do not match the expectations of these two properties. The recently proposed Equilibrium Model (EM) provides a quantitati

While direct toxicity assessment (DTA) is now widely recognised as a useful tool for environmental risk assessment, many existing tests fail to meet end-user needs. This article describes the significant progress made to the MICREDOX® DTA assay, dev

Hydrothermal vent ecosystems support diverse life forms, many of which rely on symbiotic associations to perform functions integral to survival in these extreme physicochemical environments. Epsilonproteobacteria , found free-living and in intimate a

The temperature dependence of the dynamics of mesophilic and thermophilic dihydrofolate reductase is examined using elastic incoherent neutron scattering. It is demonstrated that the distribution of atomic displacement amplitudes can be derived from

Arising from careful measurements of the thermal behaviour of enzymes, a new model, the Equilibrium Model, has been developed to explain more fully the effects of temperature on enzymes. The model describes the effect of temperature on enzyme activit

The "Equilibrium Model" has provided new tools for describing and investigating enzyme thermal adaptation. It has been shown that the effect of temperature on enzyme activity is not only governed by deltaG(double dagger)(cat) and deltaG(double dagger

Recent measurements have demonstrated enzyme activity at hydrations as low as 3%. The question of whether the hydration-induced enzyme flexibility is important for activity is addressed by performing picosecond dynamic neutron scattering experiments

The way that enzymes respond to temperature is fundamental to many areas of biotechnology. This has long been explained in terms of enzyme stability and catalytic activation energy, but recent observations of enzyme behaviour suggest that this pictur
