Toxicity of dihydroxyacetone is exerted through the formation of methylglyoxal in Saccharomyces cerevisiae: effects on actin polarity and nuclear division
Lead induces the up-regulation of the protein arginine methyltransferase 5 possibly by its promoter demethylation
Guarding the gateway to histidine biosynthesis in plants: Medicago truncatula ATP-phosphoribosyltransferase in relaxed and tense states
A schematic representation of the steps in involved in single-molecule calligraphy using the TERI (trapping the enzymatic reaction intermediate) technique used by Hazra et al. to track force-activated reaction pathways in real time. In this issue, these authors report on the mechanism of the sortase A enzymatic reaction that, counter-intuitively, accelerates bacterial adhesion under shear tension. For details, see pages 2611–2620.
