abstract = {The octa-peptide angiotensin II (Ang II,
(H2N-Asp–Arg–Val–Tyr–Ile–His–Pro–Phe–COOH))
is one of the key player on blood pressure regulation in
mammals.Predominantly binding to the Angiotensin type 1 and
2 receptors, the hormone is oneof several peptide ligands
binding to G protein coupled receptors (GPCR). The
activehormone derives from a high molecular weight precursor
sequentially cleaved by theproteases renin and the
angiotensin converting enzyme (ACE). The chemical natureof
the amino acid sequence has an impact on the behavior in the
proximity ofmembranes, demonstrated using different membrane
model systems and biophysicalmethods.Applying
electrochemical impedance spectroscopy and small angle x-ray
scattering adetailed view on the adhesion of the peptide
with model membrane surfaces wasperformed. The role of
specific amino acids involved in the interaction with
thephospholipid head group were investigated and, studying a
truncated version of AngII, Ang (1-7), the key role of the
C-terminal phenylalanine was proven. Truncation ofthe
C-terminal amino acid abolishes the binding of the peptide
to the membranesurface. A shift in pH, altering the
protonation state of the central histidine residueimpairs
the adhesion of Ang II.},
