Structural communication between the chromophore‐binding pocket and the N‐terminal extension in plant phytochrome phyB
The N‐terminal extension ( NTE ) of plant phytochromes has been suggested to play a functional role in signaling photoinduced structural changes. Here, we use resonance Raman spectroscopy to study the effect of the NTE on the chromophore structure of B‐type phytochromes from two evolutionarily dista...

Here, we use resonance Raman spectroscopy to study the effect of the NTE on the chromophore structure of B‐type phytochromes from two evolutionarily distant plants. NTE deletion seems to have no effect on the chromophore in the inactive Pr state, but alters the torsion of the C‐D ring methine bridge and the surrounding hydrogen bonding network in the physiologically active Pfr state. These changes are accompanied by a shift of the conformational equilibrium between two Pfr substates, which might affect the thermal isomerization rate of the C‐D double bond and, thus, account for the effect of the NTE on the dark reversion kinetics. | ||

Here, we use resonance Raman spectroscopy to study the effect of the NTE on the chromophore structure of B‐type phytochromes from two evolutionarily distant plants. NTE deletion seems to have no effect on the chromophore in the inactive Pr state, but alters the torsion of the C‐D ring methine bridge and the surrounding hydrogen bonding network in the physiologically active Pfr state. These changes are accompanied by a shift of the conformational equilibrium between two Pfr substates, which might affect the thermal isomerization rate of the C‐D double bond and, thus, account for the effect of the NTE on the dark reversion kinetics.</subfield></datafield><datafield tag="540" ind1=" " ind2=" "><subfield code="a">Nutzungsrecht: © 2017 Federation of European Biochemical Societies</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">resonance Raman spectroscopy</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">plant phytochrome</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">N‐terminal extension</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">chromophore structure</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Buhrke, David</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fernandez Lopez, Maria</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shenkutie, Sintayehu Manaye</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Horsten, Silke</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Essen, Lars‐Oliver</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hughes, Jon</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hildebrandt, Peter</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">FEBS letters</subfield><subfield code="d">Amsterdam [u.a.] : Elsevier, 1968</subfield><subfield code="g">591(2017), 9, Seite 1258-1265</subfield><subfield code="w">(DE-627)129522023</subfield><subfield code="w">(DE-600)212746-5</subfield><subfield code="w">(DE-576)014938014</subfield><subfield code="x">0014-5793</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:591</subfield><subfield code="g">year:2017</subfield><subfield code="g">number:9</subfield><subfield code="g">pages:1258-1265</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">http://dx.doi.org/10.1002/1873-3468.12642</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://onlinelibrary.wiley.com/doi/10.1002/1873-3468.12642/abstract</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHY</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-CHE</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHA</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-DE-84</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">591</subfield><subfield code="j">2017</subfield><subfield code="e">9</subfield><subfield code="h">1258-1265</subfield></datafield></record></collection>

Structural communication between the chromophore‐binding pocket and the N‐terminal extension in plant phytochrome phyB |
abstract |
The N‐terminal extension ( NTE ) of plant phytochromes has been suggested to play a functional role in signaling photoinduced structural changes. Here, we use resonance Raman spectroscopy to study the effect of the NTE on the chromophore structure of B‐type phytochromes from two evolutionarily distant plants. NTE deletion seems to have no effect on the chromophore in the inactive Pr state, but alters the torsion of the C‐D ring methine bridge and the surrounding hydrogen bonding network in the physiologically active Pfr state. These changes are accompanied by a shift of the conformational equilibrium between two Pfr substates, which might affect the thermal isomerization rate of the C‐D double bond and, thus, account for the effect of the NTE on the dark reversion kinetics. |
