Chromophore selectivity in bacterial phytochromes

Publikováno v: European Journal of Biochemistry. 271:1117-1126

Bacterial phytochromes (Bphs) are ancestors of the well characterized plant photoreceptors. Whereas plant phytochromes perform their photoisomerization exclusively via a covalently bound bilin chromophore, Bphs are variable in their chromophore selec

Listening to the blue: the time-resolved thermodynamics of the bacterial blue-light receptor YtvA and its isolated LOV domain

Autor: Aba Losi, Benjamin Quest, Wolfgang Gärtner

Publikováno v: Photochemical & Photobiological Sciences. 2:759-766

YtvA is a bacterial flavo-protein related to plant phototropin. The photochemistry of YtvA and of its isolated LOV domain (YtvA-LOV) has been characterized by optical, mass spectrometric and photocalorimetric methods. The energy content (E390) of the

Autor: Wolfgang Gärtner, Nicole Tandeau de Marsac, Thérèse Coursin, Benjamin Quest, Silvia E. Braslavsky, Helena J. M. M. Jorissen, Kurt Schaffner, Anja Remberg

Publikováno v: European Journal of Biochemistry. 269:2662-2671

Two ORFs, cphA and cphB, encoding proteins CphA and CphB with strong similarities to plant phytochromes and to the cyanobacterial phytochrome Cph1 of Synechocystis sp. PCC 6803 have been identified in the filamentous cyanobacterium Calothrix sp. PCC7

First Evidence for Phototropin-Related Blue-Light Receptors in Prokaryotes

Autor: Benjamin Quest, Eugenia Polverini, Wolfgang Gärtner, Aba Losi

Publikováno v: Scopus-Elsevier

A prokaryotic protein, YtvA from Bacillus subtilis, was found to possess a light, oxygen, voltage (LOV) domain sharing high homology with the photoactive, flavin mononucleotide (FMN)-binding LOV domains of phototropins (phot), blue-light photorecepto

Recent Decisions of the European Court of Justice of the European Union on Supplementary Protection Certificates: A Few Answers-Many Questions

Autor: Markus Grammel, Benjamin Quest, Franz-Josef Zimmer

Publikováno v: BASE-Bielefeld Academic Search Engine

Supplementary Protection Certificates (SPCs) were implemented in Europe in 1993 to compensate patentees in the pharmaceutical field for the loss of effective patent terms caused by the delay in obtaining regulatory approval for the sale of medicinal

A probable link between the DedA protein and resistance to selenite

Autor: Tatiana Vallaeys, Fouzia Ledgham, Benjamin Quest, Max Mergeay, Jacques Covès

Publikováno v: Research in microbiology. 156(3)

To understand the molecular events involved in the reduction of selenite to non-toxic elemental selenium, 4000 clones of Ralstonia metallidurans CH34 were produced by random Tn5 transposon integration mutagenesis. Eight mutants were able to resist up
