The carboxin-binding site on Paracoccus denitrificans succinate:quinone reductase identified by mutation and structure comparison

Succinate:quinone reductase catalyzes electron transfer from succinate to quinone in aerobic respiration. Carboxin is a specific inhibitor of this enzyme from several different organisms. We have isolated mutant strains of the bacterium Paracoccus denitrificans that are resistant to carboxin due to mutations in the succinate:quinone reductase. The mutations identify two amino acid residues, His228

Structure and dynamics of the active site of hen egg-white lysozyme from atomic resolution neutron crystallography

Hen egg-white lysozyme (HEWL) is a widely used model protein in crystallographic studies and its enzymatic mechanism has been extensively investigated for decades. Despite this, the interaction between the reaction intermediate and the catalytic Asp52, as well as the orientation of Asn44 and Asn46 side chains, remain ambiguous. Here, we report the crystal structures of perdeuterated HEWL and D2O b

An exploratory study of Middle Stone Age and Later Stone Age site locations in Kenya’s Central Rift Valley using landscape analysis : a GIS approach

The Kenyan central rift has witnessed dramatic climatic changes over relatively short periods of time in response to global climatic changes, with the water levels of the lakes within the rift rising and falling with these changing conditions. There is considerable evidence showing extreme wet and dry phases throughout their existence. These wet and dry phases also influenced the vegetation cover,

Spatiotemporal variation of net methane emissions and its causes across an ombrotrophic peatland : a site study from Southern Sweden

Naturliga metanutsläpp sker från våra våtmarker världen över. Metan produceras naturligt genom nedbrytning i de syrefria förhållanden som en våtmark erbjuder. För att bättre kunna modellera och skala upp hur mycker metan som faktiskt släpps ut från dessa våtmarker måste ytterligare förståelse skapas över varför metanutsläppen varierar så kraftigt både i tid och rum. Denna studie försöker öka först

The Active Site of a Carbohydrate Esterase Displays Divergent Catalytic and Noncatalytic Binding Functions

Multifunctional proteins, which play a critical role in many biological processes, have typically evolved through the recruitment of different domains that have the required functional diversity. Thus the different activities displayed by these proteins are mediated by spatially distinct domains, consistent with the specific chemical requirements of each activity. Indeed, current evolutionary theo

Effect of A/B-site substitution on oxygen production performance of strontium cobalt based perovskites for CO2 capture application

Oxy-fuel combustion is one of the proposed technologies which have the potential to achieve zero CO2 emission. Strontium cobalt based perovskite oxygen carriers are promising materials for air separation with a high selectively for oxygen. And these perovskites can produce an oxygen enriched carbon dioxide stream for an oxy-fuel combustion process. The relatively low oxygen production yield may be
