People spend a significant amount of time in their cars (US: 86 minutes/day, Europe: 43 minutes/day) while commuting, shopping, or traveling. Hence, the variety of entertainment in the car increases, and many vehicles are already equipped with displays, allowing for watching news, videos, accessing the Internet, or playing games. At the same time, the(More)
The pseudotetrasaccharide acarbose is a medically relevant secondary metabolite produced by strains of the genera Actinoplanes and Streptomyces. In this study gene products involved in acarbose metabolism were identified by analyzing the cytosolic and extracellular proteome of Actinoplanes sp. SE50/110 cultures grown in a high-maltose minimal medium. The(More)
Colloidal haze is a serious quality defect of bright beers that considerably reduces their shelf life and is thought to be triggered by hordeins, a class of proline-rich barley proteins. In this work, the proteomes of fresh and old beers were investigated in bottled pilsners and compared to the protein inventory of haze to identify specific haze-active(More)
The black rot pathogen Xanthomonas campestris utilizes molecules of the diffusible signal factor (DSF) family as signals to regulate diverse processes contributing to virulence. DSF signal synthesis and transduction requires proteins encoded by the rpf gene cluster. RpfF catalyzes DSF synthesis, whereas the RpfCG two-component system links the perception of(More)
At a molecular level, the regulation of many important cellular processes is still obscure in xanthomonads, a bacterial group of outstanding relevance as world-wide plant pathogens and important for biotechnology as producers of the polysaccharide xanthan. Transcriptome analysis indicated a sucrose-dependent regulation of 18 genes in Xanthomonas campestris(More)
Two-dimensional PAGE (2D-PAGE) is a key technique for the separation of complex protein samples to survey the protein inventory of prokaryotic microorganisms. Although the preparation of proteins is a critical step in 2D gel experiments, its effect on the outcome of proteome data is often underestimated. In this work, we show that the choice of protein(More)
