Abstract
SSO1273 of Sulfolobus solfataricus was identified as a cell surface-bound protein by a proteomics approach. Sequence inspection of the genome revealed that the open reading frame of sso1273 is associated in an operon-like structure with genes encoding all the remaining components of a canonical prot...

Abstract
Methanohalophilus portucalensis FDF1 can grow over a range of external NaCl concentrations, from 1.2 to 2.9 mol/L. Differential gene expression in response to long-term hyper-salt stress (3.1 mol/L of NaCl) and hypo-salt stress (0.9 mol/L of NaCl) were compared by differential display RT-PCR. Fourte...

Abstract
During signal transduction by two-component regulatory systems, sensor kinases detect and encode input information while response regulators (RRs) control output. Most receiver domains function as phosphorylation-mediated switches within RRs, but some transfer phosphoryl groups in multistep phosphor...

Abstract
Comparative transcriptomic analysis of autotrophic, heterotrophic, and mixotrophic growth of the archaeon Metallosphaera sedula (70 degrees C, pH 2.0) revealed candidates for yet-to-be-confirmed components of the 3-hydroxypropionate/4-hydroxybutyrate pathway and implicated a membrane-bound hydrogena...

Abstract
We have reconstructed the primary transcriptome of Sulfolobus solfataricus P2, one of the most widely studied model archaeal organisms. Analysis of 625 million bases of sequenced cDNAs yielded a single-base-pair resolution map of transcription start sites and operon structures for more than 1000 tra...

Abstract
A microchip array encompassing probes for 14,010 genes of Drosophila melanogaster was used to analyze the effect of juvenile hormone (JH) on genome-wide gene expression. JH is a member of a group of insect hormones involved in regulating larval development and adult reproductive processes. Total RNA...

Abstract
Attachment of microorganisms to surfaces is a prerequisite for colonization and biofilm formation. The hyperthermophilic crenarchaeote Sulfolobus solfataricus was able to attach to a variety of surfaces, such as glass, mica, pyrite, and carbon-coated gold grids. Deletion mutant analysis showed that...

Our results indicate that the core promoter structures of some archaeal genes may possess a combination of eukaryotic- and bacterial-like features, and moreover, suggest a possible evolutionary relationship between basal transcription signals and transcription mechanisms of Archaea and the other two...

A. niger beta-glucosidase was successfully expressed in P. pastoris and the recombinant produced gentiooligosaccharide from glucose. In addition, the main operation parameters of this enzymatic conversion were optimized. At 80% glucose, 60 degrees C, pH 4.5, 1 mmol/L K+, 60 U beta-glucosidase per gr...

Abstract
We have created mutants with either ota or otb deleted to address their role in salt adaptation. The mutants were not impaired in growth at low or high salt, neither at 37 degrees C nor at lower temperatures. However, the Deltaota mutant was completely defective in glycine betaine transport demonstr...

Abstract
We show that, in stark contrast to its eukaryotic counterparts, multiple substitutions in the C-terminal stirrup of Methanocaldococcus jannaschii (Mja) TBP do not completely abrogate basal transcription. Using DNA affinity cleavage, we show that, by assembling TFB through its conserved N-terminal st...

The study seeks to identify putative regulatory motifs in the upstream regions of 13 functional groups of genes expressed in the intraerythrocytic developmental cycle of Pf. Three motif-discovery programs were used for the purpose, and motifs were searched for only on the gene coding strand. Four mo...

Six to ten percent of the proteome changed significantly with each nutrient limitation. H2 limitation increased the abundance of a wide variety of prote...

In Eukarya, N glycosylation involves the actions of enzymes working on both faces of the endoplasmic reticulum membrane. The steps of bacterial N glycosylation, in contrast, transpire essentially on the cytoplasmic side of the plasma membrane, with only transfer of the assembled glycan to the target...

Abstract
We have named the operon ups operon for UV-inducible pili operon of Sulfolobus. Overexpression of the pre-pilins, Ups-A/B (SSO0117/0118) in Sulfolobus resulted in production of extremely long filaments. Pronounced cellular aggregation was observed and quantified upon UV treatment. This aggregation w...
