| 500 | _ | _ | |a The research project was supported by a grant of the Deutsche Forschungsgemeinschaft, SFB 533, TP B11, which is gratefully acknowledged. We would like to acknowledge particularly Joachim Dorbecker and Reinhold Funer who helped to build the 2 kbar pressure cell and the platform for TOFTOF. We would like to thank Jandal Ringe for his help on TOFTOF during our experiments. The ANTARES team, especially Martin Muhlbauer and Elbio Calzada, are thanked for allowing us to use some beam time for neutronography measurements, and to Robert Georgii for beamtime on MIRA to perform the SANS characterization measurements. Finally, we would like to thank Alan Soper for useful discussions. |
| 520 | _ | _ | |a Pressure is a ubiquitous physical parameter in life and is commonly used in the life sciences to study new protein folding pathways or association-dissociation phenomena. In this paper, an investigation of the influence of pressure on hemoglobin, a multimeric protein, at the picosecond time scale is presented using time-of-flight neutron scattering. The aim is to observe the influence of pressure on the translational diffusion and internal motions of hemoglobin in a concentrated solution and a possible dissociation of the subunits as suggested by Pin et al. (Biochemistry 29:9194, 1990) using fluorescence spectroscopy. A new flat 2 kbar pressure cell made of an aluminum alloy has been used, which allowed the effect of pressure to be studied with minimum background contribution. Within this range of pressure, the effect of this physical parameter on global diffusion can be explained in terms of the change in the water buffer viscosity and an oligomerization of hemoglobin subunits, whereas the internal motions were less affected. |
