abstract = {Lipid-protein interactions are known to play a crucial role
in structure and physiological activity of integral membrane
proteins. However, current technology for membrane protein
purification necessitates extraction from the membrane into
detergent micelles. Also, due to experimental protocols,
most of the data available for membrane proteins is obtained
using detergent-solubilized samples. Stable solubilization
of membrane proteins is therefore an important issue in
biotechnology as well as in biochemistry and structural
biology. An understanding of solubilization effects on
structural and functional properties of specific proteins is
of utmost relevance for the evaluation and interpretation of
experimental results. In this study, a comparison of
structural and kinetic data obtained for the archaebacterial
photoreceptor/transducer complex from Natronomonas pharaonis
(NpSRII/NpHtrII) in detergent-solubilized and
lipid-reconstituted states is presented. Laser flash
photolysis, fluorescence spectroscopy, and electron
paramagnetic resonance spectroscopy data reveal considerable
influence of solubilization on the photocycle kinetics of
the receptor protein and on the structure of the transducer
protein. Especially the protein-membrane proximal region and
the protein-protein interfacial domains are sensitive
towards non-native conditions. These data demonstrate that
relevance of biochemical and structural information obtained
from solubilized membrane proteins or membrane protein
complexes has to be evaluated carefully.},
