Xanthomonas campestris attenuates virulence by sensing light through a bacteriophytochrome photoreceptor
(Wiley Blackwell Publishing, Inc, 2016-09)
Phytochromes constitute a major photoreceptor family found in plants, algae, fungi, and prokaryotes, including pathogens. Here, we report that Xanthomonas campestris pv. campestris (Xcc), the causal agent of black rot ...
Crystallization and preliminary X-ray characterization of the full-length bacteriophytochrome from the plant pathogen Xanthomonas campestris pv. campestris
(John Wiley & Sons Inc, 2014-12)
Phytochromes give rise to the largest photosensor family known to date. However, they are underrepresented in the Protein Data Bank. Plant, cyanobacterial, fungal and bacterial phytochromes share a canonical architecture ...
Time-Resolved Energetics of Photoprocesses in Prokaryotic Phytochrome-Related Photoreceptors
(American Society for Photobiology, 2017-05)
Time-resolved photoacoustics (PA) is uniquely able to explore the energy landscape of photoactive proteins and concomitantly detects light-induced volumetric changes (ΔV) accompanying the formation and decay of transient ...
A spectroscopy-based methodology for rapid screening and characterization of phytochrome photochemistry in search of Pfr- favoured variants
(Grupo Argentino de Fotobiología, 2020)
Phytochromes are photosensitive proteins with a covalently bound open-chain chromophore that can switch between two principal states: red-light absorbing Pr and far-red light absorbing Pfr. Our group has previously shown ...
A Spectroscopy-based Methodology for Rapid Screening and Characterization of Phytochrome Photochemistry in Search of Pfr-favored Variants
(Wiley Blackwell Publishing, Inc, 2020-07)
Phytochromes are photosensitive proteins with a covalently bound open-chain chromophore that can switch between two principal states: red light absorbing Pr and far-red light absorbing Pfr. Our group has previously shown ...
Structure of the Full-Length Bacteriophytochrome from the Plant Pathogen Xanthomonas campestris Provides Clues to its Long-Range Signaling Mechanism
(Academic Press Ltd-elsevier Science Ltd, 2016-09-25)
Phytochromes constitute a major superfamily of light-sensing proteins that are reversibly photoconverted between a red-absorbing (Pr) and a far-red-absorbing (Pfr) state. Bacteriophytochromes (BphPs) are found among ...
Mutational analysis of Deinococcus radiodurans bacteriophytochrome reveals key amino acids necessary for the photochromicity and proton exchange cycle of phytochromes
(American Society for Biochemistry and Molecular Biology, 2008-05)
The ability of phytochromes (Phy) to act as photointerconvertible light switches in plants and microorganisms depends on key interactions between the bilin chromophore and the apoprotein that promote bilin attachment and ...
A study on Pr-induced variants of XccBphP bacteriophytochrome photoreceptor from Xanthomonas campestris
(Grupo Argentino de Fotobiología, 2020)
Red and far-red light sensing bacteriophytochrome photoreceptor (BphP) and blue light sensing LOV domain proteins have been showed to play key roles in bacterial physiology and in virulence factors (VFs) modulation. We ...
Structural and functional analyses of Pr-induced variants of XccBphP bacteriophytochrome from Xanthomas campestris
(Tech Science Press, 2021)
Photoreceptors are able to detect light and transduce that signal generating a cellular response. Among them are the red/far red light sensing bacteriophytochromes (BphP). These bilin-binding proteins have the ability to ...
The Chromophore Structure of the Cyanobacterial Phytochrome Cph1 As Predicted by Time-Dependent Density Functional Theory
(AMER CHEMICAL SOC, 2008-12-25)
The UV-vis absorption spectra of the photoreceptor chromophores biliverdin (BV) in the ZZZssa conformation and the phycocyanobilin (PCB) with conformations ZZZssa and ZZZasa have been investigated by means of time-dependent ...
