13. Structural insights into the regulation of PDK1 by phosphoinositides and inositol phosphates
3-phosphoinositide-dependent protein kinase-1 (PDK1) phosphorylates and activates many kinases belonging to the AGC subfamily. PDK1 possesses a C-terminal pleckstrin homology (PH) domain that interacts with PtdIns(3,4,5)P3/PtdIns(3,4)P2 and with lower affinity to PtdIns(4,5)P2. We describe the crystal structure of the PDK1 PH domain, in the absence and prese

14. Intracellular Survival of Brucella spp. in Human Monocytes Involves Conventional Uptake but Special Phagosomes
Brucella spp. are facultative intracellular parasites of various mammals, including humans, typically infecting lymphoid as well as reproductive organs. We have investigated how B. suis and B. melitensis enter human monocytes and in which compartment they survive. Peripheral blood monocytes readily internalized nonopsonized brucellae and killed most of them

15. The chloroplast and mitochondrial genome sequences of the charophyte Chaetosphaeridium globosum: Insights into the timing of the events that restructured organelle DNAs within the green algal lineage that led to land plants
The land plants and their immediate green algal ancestors, the charophytes, form the Streptophyta. There is evidence that both the chloroplast DNA (cpDNA) and mitochondrial DNA (mtDNA) underwent substantial changes in their architecture (intron insertions, gene losses, scrambling in gene order, and genome expansion in the case of mtDNA) during the evolution

16. Role of Decay-Accelerating Factor Domains and Anchorage in Internalization of Dr-Fimbriated Escherichia coli
Dr-fimbriated Escherichia coli capable of invading epithelial cells recognizes human decay-accelerating factor (DAF) as its cellular receptor. The role of extracellular domains and the glycosylphosphatidylinositol anchor of DAF in the process of internalization of Dr+ E. coli was characterized in a cell-cell interaction model. Binding of Dr+ E. coli to the s
