Aerolysin secreted by the human pathogen Aeromonas hydrophila belongs to a group of bacterial toxins that are hemolytic and form channels in biological membranes. The toxin is secreted as an inactive precursor proaerolysin that must be proteolytically proc ...
Rhodopsin-transducin coupling was used as an assay to investigate a laterally patterned membrane reconstituted with a receptor and its G protein. It served as a model system to show the feasibility to immobilize G protein-coupled receptors on solid support ...
Raman spectroscopy and x-ray diffraction are used to investigate the influence of surface charges on the structure of ionizable lipid membranes of dimyristoylmethylphosphatidic acid. The membrane surface charge d. is regulated by varying the pH of the aq. ...
Membrane proteins fulfill many central functions in the biological membrane. The insertion process of these proteins and their structure, which are intimately linked to their function, are not yet well understood. As a model we studied three proteins recon ...
The microscopic description of the interface of colloidal particles in solution is essential to understand and predict the stability of these systems, as well as their chemical and electrochemical reactivity. However, this description often relies on the u ...
For the first time, the std. free energy change, DG Deg, of a membrane-inserting protein with a leader sequence has been detd. exptl., using M13 procoat protein as an example. The partition coeff. for the distribution of the procoat protein between the aq. ...
A new strategy for the reversible formation of supported lipid bilayers is introduced. It uses an extension of immobilized metal ion affinity chromatog. technol., which depends on the reversible formation of complexes between metal ion binding chelator gro ...
The interaction of mitochondrial creatine kinase (Mi-CK; EC 2.7.3.2) with phospholipid monolayers and spread mitochondrial membranes at the air/water interface has been investigated. It appeared that Mi-CK penetrated into these monolayers as evidenced by a ...
