Tilt and rotation angles of a transmembrane model peptide as studied by fluorescence spectroscopy.

Tilt and rotation angles of a transmembrane model peptide as studied by fluorescence spectroscopy.

In this research the membrane orientation of a tryptophan-flanked model peptide, WALP23, was decided by utilizing peptides that have been labeled at completely different positions alongside the sequence with the environmentally delicate fluorescent label BADAN. The fluorescence properties, reflecting the native polarity, have been used to find out the lean and rotation angles of the peptide…
