Figure 2. Peptide-porphyrin binding by absorbance spectroscopy.

Figure 2

The binding of the TPPS42− to the peptides (A) PBP, (B) PBP-W11, (C) PBP-W18, (D) PBP-X, or (E) PBP-A was assessed by absorbance spectroscopy. In all panels the absorbance of 3 μM TPPS42− alone is shown in black while the absorbance spectrum after addition of 1 μM peptide is shown in green. (F) Chemical structure of TPPS42−
