LUV-lacticin Q interaction evaluated by blue shift of tryptophan fluorescence^a

Condition	Mean ± SD of fluorescence peak of lacticin Q (nm) at indicated time point (min)
	1	3	10
Buffer	342.3 ± 0.3	342.9 ± 0.3	342.9 ± 0.5
PC-PG	335.7 ± 0.3	336.1 ± 0.3	336.0 ± 0.2
PE-PG-LPS	337.4 ± 1.2	336.3 ± 0.7	336.2 ± 0.4

^aLacticin Q and LUVs were mixed in buffer A (as described in the legend to Fig. 3) at 30°C. Excitation and emission wavelengths were set at 290 and 300 to 400 nm, respectively. The fluorescence spectrum of the LUVs was subtracted from that of the LUV-lacticin Q mixture.
