FIG. 5.
Evidence for tighter versus looser packing of the self-assemblies. (A) Shown are the changes in light-scattering intensities after S. aureus (105 CFU/ml) was added to the OAK solutions (200 μM) in PBS. (B) DSC measurements upon heating of 2.4 mM solutions of the analogous OAKs. Shown are the results of representative runs from at least two independent experiments showing a gel-to-liquid transition temperature of 51°C ± 0.4°C for C16K-β12 (solid line) but not for c16(ω7)KKc12K (dotted line). Cp, heat capacity; kcal, kilocalories.
