Schematic of membrane-associated FP-Hairpin at pH 7. There is a SHB and antiparallel β sheet FP structure so FP-Hairpin minimally oligomerizes as a dimer of trimers. The FP membrane location is chosen to be the same as the 23-residue HFP which lacks the SHB. The FP region binds negatively-charged membranes at pH 7 whereas the negatively charged SHB region may not bind these membranes.
