Spin cascade and doming in ferric hemes: Femtosecond X-ray absorption and X-ray emission studies

Majed Chergui, Christopher Alexander Arrell, Wojciech Gawelda, Giulia Fulvia Mancini, Camila Bacellar Cases Da Silveira, Frederico Alves Lima, Dominik Kinschel, Oliviero Cannelli, Jérémy Raymond Jean Maurice Rouxel, Rebecca Ann Ingle

The structure-function relationship is at the heart of biology, and major protein deformations are correlated to specific functions. For ferrous heme proteins, doming is associated with the respiratory function in hemoglobin and myoglobins. Cytochrome c (C ...

Observation of the decay Lambda(0)(b) -> Lambda(+)(c)p(p)over-bar pi(-)

Olivier Schneider, Aurelio Bay, Guido Haefeli, Christoph Frei, Tatsuya Nakada, Frédéric Blanc, Michel De Cian, Luca Pescatore, François Fleuret, Chitsanu Khurewathanakul

The decay Lambda(0)(b) -> Lambda(+)(c)p (p) over bar pi(-) is observed using pp collision data collected with the LHCb detector at centre-of-mass energies of root s = 7 and 8 Tev, corresponding to an integrated luminosity of 3 fb(-1). The ratio of branchin ...

NO binding kinetics in myoglobin investigated by picosecond Fe K-edge absorption spectroscopy

Majed Chergui, Marco Eli Reinhard, Thomas James Penfold, Camelia Borca, Frederico Alves Lima, Mercedes Hannelore Rittmann-Frank, Jochen Rittmann, Mahsa Silatani

Diatomic ligands in hemoproteins and the way they bind to the active center are central to the protein's function. Using picosecond Fe K-edge X-ray absorption spectroscopy, we probe the NO-heme recombination kinetics with direct sensitivity to the Fe-NO bi ...

Probing the electronic and geometric structure of ferric and ferrous myoglobins in physiological solutions by Fe K-edge absorption spectroscopy

Majed Chergui, Ursula Röthlisberger, Ivano Tavernelli, Thomas James Penfold, Marco Eli Reinhard, Frederico Alves Lima

We present an iron K-edge X-ray absorption study of carboxymyoglobin (MbCO), nitrosylmyoglobin (MbNO), oxymyoglobin (MbO(2)), cyanomyoglobin (MbCN), aquomet myoglobin (metMb) and unligated myoglobin (deoxyMb) in physiological media. The analysis of the XAN ...

X-ray Absorption Spectroscopy of Ground and Excited Rhenium–Carbonyl–Diimine Complexes: Evidence for a Two-Center Electron Transfer

Majed Chergui, Ursula Röthlisberger, Ivano Tavernelli, Thomas James Penfold, Van Thai Pham, Amal El Nahhas, Renske Marjan van der Veen, Frederico Alves Lima

Steady-state and picosecond time-resolved X-ray absorption spectroscopy is used to study the ground and lowest triplet states of ReX(CO)(3)(bpy), X = Etpy (n = 1), Cl, or Br (n = 0). We demonstrate that the transient spectra at both the Re L3- and Br ...
