The structure of a pH-sensing mycobacterial adenylyl cyclase holoenzymeIvo Tews
Biochemiezentrum der Universität Heidelberg, Im Neuenheimer Feld 328, 69120 Heidelberg, Germany
Science 308:1020-3. 2005..Two alpha helices serve as molecular switches. Mutagenesis is consistent with a regulatory role of the structural transition, and we suggest that the transition is regulated by pH...

Heidelberg University Biochemistry Center, Im Neuenheimer Feld 328, 69120 Heidelberg, Germany
Structure 16:585-96. 2008..Potential binding sites for interactions within the Toc translocon or with precursor proteins can be derived from the structures... - A direct role for phosphatidylinositol-4,5-bisphosphate in unconventional secretion of fibroblast growth factor 2Koen Temmerman
Heidelberg University Biochemistry Center, Im Neuenheimer Feld 328, 69120 Heidelberg, Germany

Abteilung Pharmazeutische Biochemie, Fakultät für Chemie und Pharmazie, Universitat Tubingen, Germany
FEBS J 273:4219-28. 2006..These regulatory properties open the possibility that novel modes of cAMP-mediated signal transduction exist in the pathogen... - Vitamin B6 biosynthesis by the malaria parasite Plasmodium falciparum: biochemical and structural insightsMartin Gengenbacher
, , Im Neuenheimer Feld 324, D-69120 Heidelberg, Germany
J Biol Chem 281:3633-41. 2006..62 A. The obstruction of the oxyanion hole indicates that Pdx2 is in a resting state and that activation occurs upon Pdx1-Pdx2 complex formation... - The molecular chaperone Hsp90 delivers precursor proteins to the chloroplast import receptor Toc64Soumya Qbadou
Botanik, , , Germany
EMBO J 25:1836-47. 2006..We propose that Toc64 acts as an initial docking site for Hsp90 associated precursor proteins. We outline a mechanism in which chaperones are recruited for a specific targeting event by a membrane-inserted receptor... - The N-terminal cysteine pair of yeast sulfhydryl oxidase Erv1p is essential for in vivo activity and interacts with the primary redox centreGötz Hofhaus
Institut für Biochemie und Biologisch Medizinisches Forschungszentrum, Heinrich Heine Universitat Dusseldorf, Germany
Eur J Biochem 270:1528-35. 2003..Variations in dimer formation and unique colour changes of mutant proteins argue in favour of an interaction between the N-terminal cysteine pair with the redox centre of the partner monomer... - Solubilization of aggregated proteins by ClpB/DnaK relies on the continuous extraction of unfolded polypeptidesChristian Schlieker
ZMBH, Universitat Heidelberg, Im Neuenheimer Feld 282, Heidelberg D 69120, Germany

J Mol Biol 374:732-48. 2007..subtilis Pdx2. The swap mutant also partially elicits glutaminase activity in BsPdx2, demonstrating that formation of the protein complex interface via alphaN and catalytic activation of the glutaminase are linked processes... - Two independent routes of de novo vitamin B6 biosynthesis: not that different after allTeresa B Fitzpatrick
ETH Zurich, Institute of Plant Sciences, 8092 Zurich, Switzerland
Biochem J 407:1-13. 2007..Surprisingly, this comparison reveals that the key biosynthetic enzymes of both pathways are, in fact, very similar both structurally and mechanistically... - Functional analysis of PDX2 from Arabidopsis, a glutaminase involved in vitamin B6 biosynthesisMarina Tambasco-Studart
